Question

What is the x-coordinate of the x-intercept of the line that passes through points (-5, 3) and (1, -3)

Answer 1

slope of lin =y2-y1/x2-x1
=-3-3/1+5
=-6/6
=-1
equation of line is
y=mx+c
m=slope
y=-1x+c
as line passes thru (1,-3)
-3=-1+c
c=-2
y=-1x-2
to get x intercept keep y=0
-x-2=0
x=-2
point is(-2,0)
