Set up 6n + 4 = 34, subtract 4: 6n = 30, divide by 6: n = 5.

Question 4

What is the slope of the line y = 3x − 2?

Accepted Answer

3

Answer

In slope-intercept form y = mx + b, the coefficient of x is the slope, so slope = 3.

Question 5

If f(x) = 2x + 5, what is f(4)?

Accepted Answer

13

Answer

Substitute x = 4: f(4) = 2(4) + 5 = 8 + 5 = 13.
