30. write an equation in point-slope form for the line through the given point with the given slope. (-7,9); m=4/5

a. y+7= 4/5(x-9)
b. y-7=4/5(x+9)
c. y-9=4/5(x+7
d. y+9=4/5(x-7)

one way is to plot 2 points and connect them which is what the answer choices seem to be doing

it seems to be using the y intercept and the slope

y=mx+b, m=slope, b=y-intercept (where the line hits the y axis)

slope=rise/run

y-intercept is where the line croses the y axis which is the y value where x=0

you seem to have given the wrong slope (you didn't put a number in front of te x, it should be 2/3 or 3/2 looking at the answer options)

y=? x-1

m=? because of your fault

b=-1

so it has a slope of ? and y intercept of -1, meaning it pases through (0,-1)

so draw point (0,-1) (so answer is one of the first 2 option)

if slope is 2/3, then go up 2 and right 3 then draw line through those 2 points

if slope is 3/2, then go up 3 and right 2 then draw line through those 2 points

the anwser is x< -17/2

$205,000 here you go i had to guess it but i got it correct so yeah
