How many hours are in 186 minutes express this as a mixed number and as a decimal

answer:

y = -3/2x +7/2

step-by-step explanation:

when we have two points, we need to find the slope.

slope is given by

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

    = (5--1)/ (-1-3)

    = (5+1)/ (-4)

    = 6/-4

    = -3/2

we have the slope and a point

using the point slope form of a line

y-y1 = m(x-x1)

y--1 = -3/2( x-3)

y+1 = -3/2(x-3)

they usually want the line written in slope intercept form (y=mx+b)

distribute the -3/2

y+1 = -3/2x +9/2

subtract 1

y+1-1 = -3/2x +9/2 -2/2

y = -3/2x +7/2
