Answer:
Rate of change: 2/15, Initial value: 8, Equation: y=2/15x+8
Explanation:
To find the rate of change, you find two points on the graph. (0, 8) and (15, 10). Then you plug them into the formula for finding the slope: (y2-y1)(x2/x1)=slope.
10-8/15-0=2/15
To find the initial value, you find the y -intercept, which is (0,8) so the initial value is 8.
For the equation, you already have the slope and y-intercept. So you plug the numbers into the slope-intercept form, y=mx+b, which would be y=2/15x+8.
