Question

PLZZ MHANIFA THIS THE LAST ONE its all in the pic

Answer 1

Answer:

1) Use two points to find the slope

Points from the graph

• (0, -1) and (1, 2)

Find the slope:

• m = (2 - (-1))/(1 - 0) = 3

Slope is 3, y-intercept is -1

The line is:

• y = 3x - 1

This is non-proportional as not passing through the origin (0, 0)

2) One point is sufficient to determine the slope as the line passes through the origin

Point (5, 2)

The slope is

• m = 2/5

Line is:

• y = 2/5x

This is proportional
