Question: how to find the x and y intercepts with 2 points?
Answer: Since the value of m is unknown, the first step is to calculate the slope of the line. ... 
Choose (x1, y1) = (–2, –5) and (x2, y2) = (6, 1).
By substituting the value obtained in the slope-intercept form, you get the equation:
STEP 4: The value of b is still unknown. ... 
STEP 5: Now, solve the equation for b.
