Use a table of values to graph the following quadratic equation. y=‒x2+4x‒3 what is the vertex of this quadratic equation? (a.) (‒1, 9) (b). (2, 1) (c.) (‒4, 3) (d). (1, ‒9)

c. y = 1/4 x + 5

step-by-step explanation:

first, put the equation of the line on the graph into slope-intercept form

(y = mx + b):   y = -4x + 8

second, a perpendicular line has to have "an opposite/reciprocal slope" to the original slope. so, find the "m" value in your original equation (it's -4, right? )

original slope: m = -4   perpendicular slope: change the sign to its opposite and find the reciprocal ("flip" the number)

new slope is now positive (b/c the original slope was negative 4), and it's 1/4 (not the original slope of 4 or 4/1)

i’m sorry but i don’t know sorry
