Answer:

The equation would be y = 1.5x + 0.5

Step-by-step explanation:

To find the equation of the line, use the point and the slope in point-slope form.

y - y1 = m(x - x1)

y - 32 = 1.5(x - 21)

y - 32 = 1.5x - 31.5

y = 1.5x + 0.5

Answer:

B, 19

Step-by-step explanation:

To find f(2), we simply plug in 2 for x in the equation: $2(3^x)+1$

We have: $2(3^2)+1=2*9+1=18+1=19$

Thus, the answer is B, 19.
