1. Solve the given system. y = x + 20 y = 6x. Put it in a fraction form
2. State the slope and y-intercept of the equation. -8x + y = -12. Put it in a fraction form
3. What is the slope of the line that passes through the points E(5, 1) and F (2, -7). m =
4. Decide which of the points is a solution. y = 2x y = x + 1 a. (1, 2) b. (2, 1) c. (-1, -2)

step-by-step explanation:

step-by-step explanation:

we have

using a graphing tool

see the attached figure

this is a quadratic equation (vertical parabola) open up

the vertex is a > vertex

the domain of the function is all real > interval (-∞,∞)

the range of the function is the > [-6.125,∞)

the function has two x->   and

the function is increasing over the > (0.25,∞)

the function is decreasing over the > (-∞,0.25)
