Find the slope and the y- intercept of the line y=2x-6

The slope is 2 and the y-intercept is -6

Step-by-step explanation:

we know that

The equation of the line in slope intercept form is equal to

where

m is unit rate or the slope of the linear equation

b is the y-intercept or initial value (value of y when the value of x is equal to zero)

In this problem we have

therefore

the slope is equal to

and

Verify

For x=0

---> is ok

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!
