Problema Solution
what is the equation of the line that passes through point (5,8)and has a y-intercept of -2
Answer provided by our tutors
The y-intercept is -2 means the line goes through (0, -2).
The equation of the line though (5,8) and (0, -2) is:
y = ((-2-8)/(0-5))x - 2 (since the slope m = (y2 - y1)/(x2 - x1), b = -2 and y = mx + b)
y = 2x - 2
The equation of the line is y=2x-2.
