The unit rate is C. 50mph
Step-by-step explanation:
Take two points from the line,
I took points (1, 50) and (2, 100).
Then plug them into this formula:
y2-y1/x2-x1
Solve:
(100- 50)/(2 - 1)
100 - 50 = 50
2 - 1 = 1
50/1 = 50
So, you get C. 50mph
the graph in the attached figure
step-by-step explanation:
we have
using a graphing tool
the roots are ( x-intercepts) x=-0.5,x=1,x=3
the y-intercept is the point (0,3)
