What is the y-intercept of the line shown on the graph that represents a proportional relationship? y=-4
y=0
y=1
y=2

y=0

Step-by-step explanation:

Proportions

A direct proportion is a relation between variables where their ratio is a constant value. This means that if y and x are proportional, then:

y=k.x

Where k is the constant of proportionality.

The y-intercept can be obtained by setting x=0. Note the y-intercept of every proportional relationship is y=0.

y = −2x − 5 slope = -2
perpendicular line, slope is opposite and reciprocal so slope of of a line perpendicular to line WX = 1/2

passing point (−1, −2)
y + 2 = 1/2(x + 1)
y + 2 = 1/2 x + 1/2
y = 1/2 x - 3/2

Answer

y = 1/2 x - 3/2

y = 1 over 2 x -  3 over 2
