Question

4. What is the equation of the line that passes

through the point (6, 0) and has a slope of -3?
1) y = −3x + 6
2) y=-3x - 18
3) y=-3x - 6
4) y = −3x + 18

Answer 1

Answer: the fourth choice, or y=-3x+18

Explanation:

using the point-slope form, we can plug in the values:

y-0= -3(x-6)

distributing the right side we get

y-0=-3x+18

putting it into y=mx+b form we get y=-3x+18
