Question

Write an equation of a line in point slope form that has a slope of -3 and passes through the point
(3, -4)

Answer 1

slope-intercept form; y=mx+b
Lets start by using point-slope form;
(Y-Y1)=m(X-X1)

(x1,y1)=(3, -4) and slope=-3
Now plug in the information given;
(y+4)=-3(x-3)
y+4=-3x+9
y=-3x+9-4
y=-3x+5

Answer 8

-3 over 4 *

Answer 9

slope-intercept form; y=mx+b
Lets start by using point-slope form;
(Y-Y1)=m(X-X1)

(x1,y1)=(4, 5) and slope=-3/4
Now plug in the information given;
(y-5)=-3/4(x-4)
4y-20=-3x+12
4y=-3x+12+20
4y=-3x+32
