For 5 a, the y intercept is 2, because when x is 0, y is 2.
The growth is 5, because the y values increase by 5 whenever x is increased by 1.
For 5 b, This problem is linear because it goes up or down a set amount (it's not exponential).
Since this is a linear equation, we can use slope intercept form to represent this.
Slope intercept form is y=mx+b, where m is the slope (rise over run) and b is the y intercept.
Plugging in the slope and y-intercept, we get an equation of y=5x+2
For 5 c, we can plug 52 into the equation we just made.
52=5x+2
-2 -2
50=5x

\frac{50}{5}= \frac{5x}{5}[/tex]
10=x
Hope that helps!
