determine the rate of change (slope) and starting point (y-intercept)

Answer:
SLOPE=7 Y-INTERCEPT=0
Step-by-step explanation:
First you find the rise over run. In this case it is 14/2 (it is hard to see, but that is what it looks like.)
Then divide 14/2 which equals 7.
Therefore the slope is 7.
The line intersects the y-intercept at the point 0.
So therefore the answer is 0.
The equation for this line would be y=7x+0 or just y=7x
This would mean that the graph is proportionate.
Hope this helps!
