Answer:
y = 7x -7
Step-by-step explanation:
The slope-intercept form of an equation for a line is ...
y = mx + b
for slope m and y-intercept b. Using your given values, this becomes ...
y = 7x +(-7)
We usually write this as ...
y = 7x - 7

The <em><u>correct answer</u></em> is:
B) an exponential function with a growth factor of 2
Explanation:
An exponential function is one of the form f(x) = aˣ, where a is some constant. Exponential graphs are smooth curves.
This graph is a smooth curve. Looking at the points plotted, we have:
(0, 1); (1, 2); (2, 4); (3, 8)
The growth factor is the number we multiply each value by to find the next one. From 1 to 2, we would multiply by 2; from 2 to 4, multiply by 2; from 4 to 8, multiply by 2. This makes the growth factor 2.
