The line of best fit is y = 0.8x. choose the best representation for the y-intercept. the y-intercept of the line of the best fit shows that with no rainfall there will be no plant growth. the y-intercept of the line of the best fit shows that with no rainfall the plant growth will be approximately 0.8 inches. the y-intercept of the line of the best fit shows that the starting rainfall was approximately 0.8 inches. the y-intercept of the line of the best fit shows that when there is approximately 0.8 inches of rainfall there will be 0 plant growth.

parallel and congruent

step-by-step explanation:

the movement of translation is linear.   these have the same translation because you are using the same rule for each point of the triangle so you will see the same slope being used to get from a point on the triangle to its image.

same slope!   you should think parallel when you see those 2 word together (well unless it's the same line but it can't be because we are coming from different points here)

congruent! because each point is being moved the same distance.
