Answer:

Below

Explanation:

The line has negative slope and y-axis intercept = 2 from inspection

two points on the line are needed to calculate the slope

find two easy to work-with points

like (-3,4) and (4,-1)

slope = (y1-y2) / ( x1-x2) = (4 - -1) / ( -3-4) = -5/7

Slope intercept form y = mx +b m is slope b is intercept of y-axis

soooo ... y = -5/7 x + 2

The graph is rather fuzzy:

I looked a little longer and decided points (-4,5) and (4,-1) may be more accurate:

slope = 5--1 / -4-4 =- 6/8 so then the answer would be y = -3/4x + 2
