Problema Solution
Use the point-slope formula to write n equation of the line given the following information. Give your answer (if possible) in:
a. slope-intercept form
b. standard form
The line passes through the points (1,-3) and (-7,2)
Answer provided by our tutors
The slope = (-3-2)/(1--7) = -5/8
So we assume the equation is y = (-5/8)x + b
So
-3 = (-5/8)*1 + b
b = -19/8
So
the equation is y = (-5/8)x -19/8
