Answer 2

• A) y = 5/4x - 4

Explanation:

Slope-intercept formula

• y = mx + b, where m = slope, b = y-intercept

Slope formula

• m = (y2 - y1)/(x2 - x1)

Given points (on the graph)

• (0, -4) and (4, 1)

Slope is:

• m = (1 - (-4))/(4 - 0) = 5/4

y-intercept is

• -4 as per the first point

So the line is:

• y = 5/4x - 4

Correct answer option is: A) y = 5/4x - 4
