Find the slope that is parallel to the equation 2x +3y 15
b) find the slope that is perpendicular to the equation 2x + 3y 15

a) -2

b) 1/2

Step-by-step explanation:

2x + y = 15           Subtract 2x from both sides

y = -2x + 15           The slope is -2

Parallel lines have the same slope.

Perpendicular lines have negative inverse slopes.

-2    flips to 1/2

21/58.

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
