8. write the slope-intercept form of the equation of the line graphed below.

Step-by-step explanation:

The equation of a straight line can be represented in the slope-intercept form, y = mx + c

Where c = intercept

Slope, m =change in value of y on the vertical axis / change in value of x on the horizontal axis

change in the value of y = y2 - y1

Change in value of x = x2 -x1

y2 = final value of y

y 1 = initial value of y

x2 = final value of x

x1 = initial value of x

From the graph,

y2 = 4.5

y1 = 0.5

x2 = 2

x1 = - 2

Slope,m = (4.5 - 0.5)/(2 - - 2) = 4/4 = 1

To determine the intercept, we would substitute x = 2, y = 4.5 and m= 1,

4.5 = 1 × 2 + c = 2 + c

c = 4.5 - 2 = 2.5

The equation becomes

y = x + 2.5

answer: 1,380

step-by-step explanation:

1: you turn %15 into a decimal by moving the decimal point two places to the left.

2: and then you multiply .15 by 1,200 , which will get you 180.00

3: from there you will add 180 to 1,200

4: which will get you 1,380

hope it *im kind of slow so idk if my answer is right*

c.

step-by-step explanation:

because first you have to add the 4x, 9x, and the 7x together and you get 20x and then you add the last numbers up and you get 5and then you put the subtraction sign in there and that's how you get the answer.
