Question

A line has a slope of 7 and contains the point (5, −9).

Which equations represent the line?

Choose all answers that are correct.

A. −7x + y = −44

B. 7x – y = 44

C. (y − 9) = 7(x + 5)

D. (y + 9) = 7(x − 5)

Answer 1

conver to slope intercepf rom which is y=mx+b where m=slope and b= yintercept

so we have the oint (5,-9)
(x,y)
one solution is x=5 and y=-9 s
wwe are given the slope which is 7 so subsitue
y=7x+b
subsitute 5 for x and -9 for y
-9=7(5)+b
-9=35+b
subtract 35
-44=b
the equation si y=7x-44
find the one that workd
one of them is A and B and D
