Question

Use the graph to answer the questions in part 1-3.

Answer 1

Part 1: m = -7

Part 2: y = -7x -11

Part 3: 7x + y = -11

Explanation:

Part 1

Select 2 points, in this case (-2, 3) and (-1, -4) and then use the slope formula

m = (y2 - y1) / (x2 - x1)

m = (-4 -3) / (-1 - -2) =

m = -7/1

m = -7

Part 2

Use the point-slope form equation to find the slope-intercept form

y - y1 = m(x - x1)

y - 3 = -7(x - -2)

y = -7(x +2) +3

y = -7x -14 +3

y = -7x -11

Part 3

Move the x and y to the same side of the equation

y = -7x -11

7x + y = -11
