Question

What is an equation of the line that passes through the point (-2,-8) and has a slope of 3?

Answer 1

Answer:

y = 3x - 2

Step-by-step explanation:

Use the point-slope equation since we are given a point that the line passes through and its slope:

y - y1 = m(x - x1)

(-2, -8), m = 3

Substitute these values into the equation.

• y - (-8) = 3(x - (-2))
• y + 8 = 3(x + 2)
• y + 8 = 3x + 6
• y = 3x - 2

The equation of the line that passes through the point (-2, -8) and has a slope of 3 is y = 3x - 2.
