Question

Which of the following is the point slope equation of a line with a slope = 4/5 and a point of (-2, 1) ?

Answer 1

@Chelsea04

Answer 2

didn't I just answer this question?

Answer 3

I got B :)

Answer 4

oops! soooo sorry hold on

Answer 5

in any case,
find the slope as stated: 4/5
then substitute it into the equation: y-y1=m(x-x1)
the point: (-2,1)
-2=x1
1=y1

Answer 6

here I'll post the right one

Answer 7

get this equation into the form y=mx+b

Answer 8

y-3=9(x+10)
y=9x+90+3

Answer 9

@Chelsea04 so that's the form?

Answer 10

do you gave to solve?

Answer 11

not quite,
from y=9x+90+3 you simplify to
y=9x+93, then with the equation define m and b

Answer 12

m is 9
b is 93

Answer 13

oohhhh okay! So you add m and B? :)

Answer 14

no, no need

Answer 15

m remember is the slope
b is the y intercept

Answer 16

you just need to take it from the equation, so the answer is 9

Answer 17

Ohh thank you sooo much! I'm almost finished <3 <3

Answer 18

next?
