Question

Find the equation of the line that passes through the points (8,-5) and (4,3)

A. 2x + y = 11
B. x + y = -11
C. 5x + 8y = 4
D. 8x - 5y = 3

Answer 1

y=a(x - h)^2+k

standard form: y= - 1/2x^2+4x-5

vertex form: y= -1/2(x - 4)^2+3

slope m and y-intercept b

slope: -2

y-intercept:(0,11)

so the answer is A. your welcome
