Hello!
Slope - Intercept Form: 
<h3>Slope</h3>
The slope of the line is the rate of change, or how the graph changes in y as it changes in x.
Slope can be calculated by the formula: 
We need two points on the line to get the x and y-values. I'm going to choose points (0,5) and (4,-3).
Calculate Slope
The slope is -2.
<h3>Y-intercept</h3>
The y-intercept of the line is where the graph touches the y-axis (x = 0). It can be found by looking at the intersection of the graph and the axis.
The intersection happens at point (0,5), so the y-intercept is 5.
<h3>Equation</h3>
We found m, the slope, to be -2 and b, the y-intercept, to be 5. We can just plug it into the equation format.
Equation: 
1/7 *2 =2/7 take denominator with 1 over it and multiply by numerator
Answer: 30 mph is the answer.
Step-by-step explanation:
s = 3 miles
t = 6 minutes
so,
60 minute = 1 hour
1 minute = 1/60 hour
6 minutes = 1/60 * 6 = 0.1 hour
so
average speed = s/t
= 3/0.1 = 30 mph
