Use the slope-intercept form of the linear equation to write the equation of each line with the given slope and y-intercept. 7. slope -1; y-intercept (0, 1) 8. slope 1/2; y-intercept (0, -6) 9. slope 2; y-intercept (0, 3/4) 10. slope -3; y-intercept (0, -1/5) 11. slope 2/7; y-intercept (0, 0) 12. slope -4/5; y-intercept (0,0) show work

7. y=(-1)x+1

8. y=2x-6 (Unsure)

9. y=2x+0.75

10. y=-3x-0.2

11. y=7x+0 (Unsure)

12. -5x+0 (Unsure)

answer: b. f(x) = (x + 2)^3 (x^2 - 7x + 3)^4

step-by-step explanation:

polynomials always have as many roots as their order. this is a 4th order polynomial- hence 4 roots!

complex roots of polynomials always come in pairs. the quadratic equation has the "+/-" in that will alwaysgenerate m+ni amd m-ni, so 7-2i must be a root of this polynomial equation.

the order of the numerator and denominator are both 2. so the horizontal asymptote is y=a2/b2 =7

verticle asymptotes are the forbidden x-values. f(x) becomes undefined at x=-3 because this value will cause a zero denominator.

a graph of r(x) will have vertical asymptotes at ±1 because these values will make the denominator zero. so the domain of the function cannot include ±1.

you 're wlecome! : )
