Answer:
A. y = x + 7
Step-by-step explanation:
Slope intercept form is y = mx + b where m is the slope and b is the y-intercept
<em>It gives us the slope, so we can plug that in:</em> y = x + b
<em>Next, it gives us a point, so we can plug in the x and y into our equation and solve for b when (x, y)</em>
y = x + b
7 = (0) + b
7 = b
<em>Last, complete our equation:</em>
y = x + b
y = x + 7
The general equation for exponential growth can be written as:
where r is the growth rate.
Plugging in the given values, we get:
