Question

1) Write an equation of a line in slope intercept form with slope -3 going through the point (2, - 2). Show your work for full credit.

Answer 1

They give you a point and the slope. So, use Point-Slope form.
Then change to slope-intercept form.

Point-Slope Form:
y - y1 = m(x - x1)
y - (-2) = -3(x - 2)
y + 2 = -3(x - 2)

Change to slope intercept form:
y + 2 = -3(x - 2)
y + 2 = -3x + 6
y = -3x + 4

Hope this helps! (:
