Step 1 Slope of the line passing through (x1,y1) and (x2,y2) is given by:
m=y2y1x2x1
Given: A line is passing through (5,-5) and (-1,7).
m=7(5)15=126=2
Equation of the line is y=mx+c.
Thus, y=-2x+c.
Plug in x=5 and y=-5 in y=-2x+c.
-5=-2(5)+c
c=5
Thus, slope-intercept form of the line is:
y=-2x+5
Step 2 Answer:
Thus, slope-intercept form of the line is:
y=-2x+5
