Write the equation of the line with the given slope and y-intercept
The equation of a line is expressed as;
y = mx + b;
m is the slope and b is the y-intercept
7. m = -5, b = -6
y = mx + b
Input the parameters:
y = -5x -6
8. m = 1, b = -4
y = mx + b
Input the parameters:
y = x - 4
9. m = 0.4, b = -9
y = mx + b
Input the parameters:
y = 0.4x - 9
10. m = 0, b = 3
y = mx + b
Input the parameters:

Which equation has a slope of 2 and a y-intercept of - 5?
X a. 2x + y = -5
b. 2x - y = 5
c.X + 2y = - 10
d. X - 2y = 10
Answers
Answer:
b. 2x - y = 5
you are able to change the equation to y = 2x -5. this is then in the form of y = mx + b.
m = slope and b = y-intercept
m = 2 and b = -5
Answer
d. x - 2y = 10
Step-by-step explanation:
The answer you chose does have the correct y intercept, but the incorrect slope, it was asking for a slope of 1/2, not a slope of -2.
REMEMBER: The y intercept is when x = 0, the x intercept is when y = 0.
To find the y intercept, substitute 0 for x, and solve for y. The slope is the coefficient of x when the coefficient of y is 1.
Just convert this standard form equation into slope intercept.
Standard Form: Ax + By = C.
Slope Intercept: y = mx + b. (m is the slope, b is the y intercept)
To convert just get y by itself completely on the left side of the equation. (y has to have a coefficient of positive 1)
x - 2y = 10
-x -x
-2y = -x + 10
÷2 ÷2 ÷2
-y = -1/2x + 5
×-1 ×-1 ×-1
y = 1/2x - 5 → y = mx + b
m = 1/2, and b = -5
Find x and y. Give reasons to justify your solution.

Elyse wants to buy a new softball glove that costs $46.50. She has $15 and plans to save $5.25 each week. How many weeks will it take her to save the money?
write an equation using x as the variable
plz hurry im being timed
Answers
Answer:
$46.50 = $15+ $5.25x
it will take her 6 weeks
Step-by-step explanation:
she has $15, so that stays the same and the amount she saves each week is multiplied by the number of weeks. then solve the equation to find the value of x or the number of weeks and get 6 weeks
Answer:
6 weeks
Step-by-step explanation:
5.25 times 6 equals 31.5 plus 15 equals 46.50
The restaurant bill for Annette is $55.82.
She adds an 18% tip for the waiter.
What is the total cost of Annette's meal rounded to the nearest cent?
pls answer seriously, I'm failing this class its so hard for me :(
Answers
55.82 x 0.18 = 10.05
so the tip = $10.05
now we just add it to the original bill
55.82 + 10.05 = 65.87
so the total cost = $65.87

Answer:
x = -15/2 or -7.5
Step-by-step explanation:
6x - 4(x - 9) = 2(3 - x)
6x - 4x + 36 = 6 - 2x
2x + 36 = 6 - 2x
4x + 36 = 6
4x = -30
x = -30/4
x = -15/2

Write a slope intercept equation for line with the given characteristics m=-3/5 passes through (4,-4)
Answers
Step-by-step explanation:
Hey there!
Given;
Slope (m) = -3/5
And passes through the point(4,-4).
Now; The equation of a line in slope intercept form is y= mx+b.
So, try to bring it in y= mx+b form.
Firstly let's use one-point formula.
[tex](y - y1) = m(x - x1)[/tex]
Now, keep all values.
[tex](y + 4) = \frac{ - 3}{5} (x - 4)[/tex]
Now, simplify to get answer.
[tex]5(y + 4) = - 3(x - 4)[/tex]
[tex]5y + 20 = - 3x + 12[/tex]
[tex]5y = - 3x + 12 - 20[/tex]
[tex]5y = - 3x - 8[/tex]
[tex]y = \frac{ - 3}{5} x - \frac{8}{5} [/tex]
Therefore the equation is y = -3/5x - 8/5.

Visitors to a cinematic are either children, adults or pensioners. Ratio of children to adult visitors is 1:2 Ratio of adults to pensioners is 3:4 A stratified sample of 85 is to be taken from the cinema visitors. How many pensioners should there be in the sample?
Answers
Ratio of children, adults and pensioners is 1 : 2 : 8/3 = 3 : 6 : 8.
Let, 3x is number of children.
So, 6x is number of adults and 8x is number of pensioners.
Now,
3x + 6x + 8x = 85
17x = 85
x = 5
Therefore, number of pensioners are 8×5 = 40.
Hence, this is the required solution.

Multiply the parenthesis by the outside numbers (simplify).
2x - 10 = 4x + 4
Combine like terms (add 20 to both sides, and subtract 2x).
0 = 2x + 14
Subtract 14 from both sides of the equation.
2x = - 14
Divide both sides of the equation by 2.
x = -7
