What’s the slope and y intercept of y=-2x+7

y = mx + b

y = -2x + 7

mx = Slope

-2x = Slope

Down 2, left 1 = Slope

b = y intercept

7 = y intercept

(0,7) = y intercept

for this pair of functions g(x)=x-2 and f(x)=|x| is (g o f)(a)= |a| -2

step-by-step explanation:

g(x)=x-2

f(x)=|x|

(g o f)(a)=?

(g o f)(x)=g(f(x))

(g o f)(x)=g(|x|)

(g o f)(x)=|x|-2

(g o f)(a)=|a|-2

answer: 5100 just subtract
