The slope-intercept form of this equation would be y = 4x - 9.
(For explanation look down below)
Step-by-step explanation:
Slope-intercept form would be an equation that would look like...
y = mx + b
Where m is the slope and b is the intercept. From this form, we can understand that all we need to do is rearange the formula in a way that positive y would be on its left side. And so we get...
A) the middle of the range is 39.5%
b) the difference between the middle and the ends of the range is ±1.5%
c) less than a majority favor change. Change seems unlikely.
