What is the point-slope form of a line that has a slope of –4 and passes through the point (–3, 1)? A. y minus (negative 3) = negative 4 (x minus 1)
B. y minus 1 = negative 4 left-bracket x minus (negative 3) right-bracket
C. Negative 1 minus y 1 = negative 4 (negative 3 minus x 1)
D. 3 minus y 1 = negative 4 (1 minus x 1)

y/x of point b= y/x of point a

step-by-step explanation:

(i got the same question, this was the correct answer.)

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)
