Qual o coeficeinte angular da reta AB, referente aos pontos A(-3, 5) e B(1, -1). A.-3/2
B. 3/2
C. -3
D.1
E.-5

the answer will be

y = 3x+4

step-by-step explanation:

to find the slope

slope = (y2-y1)/ (x2-x1)

    = (-8-4)/ (-4-0)

    = -12/-4

  = 3

using the slope intercept form of a line

y= mx+b

we know the slope is 3

we know the y intercept is 4 ( the point where it crosses the y axis or x=0)

y = 3x+4

f(x)=2/3x-8, which give g(x) the greatest value.
