what is the equation in slope- intercept form of the line that passes through the points (-26 -11) and (39, 34) ?
A) y = -9/13 x + 7
B) y = -9/13 x - 7
C) y = 9/13 x + 7
D) y = 9/13 x - 7
step 1
Find out the slope
m=(34+11)/(39+26)
m=45/65
simplify
m=9/13
step 2
Find the equation in slope intercept form
y=mx+b
we have
m=9/13
point (39,34)
substitute and solve for b
34=(9/13)(39)+b
b=34-27
b=7
therefore
the equation is
y=(9/13)x+7
