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

option C
