Question

What is the equation of the line that passes through the point (3, 2) and has a slope of 4?

y = 4x - 1

y = 4x - 5

y = 4x - 10

y = 4x + 1



What is the x-intercept and y-intercept of the graph of 3x - 4y = 12?

x-intercept = (-4, 0); y-intercept = (0, 3)

x-intercept = (4, 0); y-intercept = (0, -3)

x-intercept = (0, -3); y-intercept = (4, 0)

x-intercept = (0, 3); y-intercept = (-4, 0)

Answer 1

If f(x) = x^2 + 2, find f(4).

Answer 2

\[1)y-y_1=m(x-x_1)\]

2)For x-intercept plug in y=0
For y-intercept plug in x=0

3)Just plug in 4 in place of x
