Which linear equation represents a proportional relationship? A) y = x + 2 B) y = 3x + 0.2 C) y = −0.3x D) y = −3x + 4
1 answer:
Answer:
answer is c
Step-by-step explanation:y =
−0.3x
The given equations are in slope-intercept form, y = mx + b, where b represents the y-intercept.
Proportional relationships must pass through the origin. Therefore, the y-intercept for the equation must be 0. The y-intercept for y = −0.3x is 0.
