What is the equation of the line that passes through the points (-1,-5) and a slope of -2

y = 2x + 7

Step-by-step explanation:

Use the point slope form of the equation of a straight line and substitute the point and the slope which are given.

y  −  y 1  =  m ( x − x 1 )

    ( x , y ) = ( − 1.5 )  and   m  =  2

y  −  5  =  2 ( x − ( − 1 ) )

y  −  5  =  2 x  +  2

y  =  2 x  +  2  +  5

y  =  2 x  +  7

42.4

hello from mrbilldoesmath!

answer:

25x^2 + 90x + 84

discussion:

mn(x) = m(n(x)) = m( 5x + 9) =

(5x + 9)^2 + 3 =>

25x^2 + 90x + 9^2 + 3 =

25x^2 + 90x + 84                 (as 9^2 = 9*9 = 81)

which is the second choice

p.s.   i'll be on vacation from friday, dec 22 to jan 2, 2019. have a great new year!
