Question

Find the equation of the line containing the point P and having the slope m. Write your answer in slope-intercept form.

P = (-4, -6), m = 3

Answer 1

slope-intercept form = y=mx+b

all you have to do is just substitute to find the y-intercept & form an equation

y=mx+b , ( -4,6) m=3
6=3(-4)+b
6=-12 +b
18=b

(m) slope= 3 & (b) y-intercept= 18

y=mx+b (substitute again...)

=> y=3x+18

Answer 2

thank you

Answer 3

so would y = 21

Answer 4

Why 21?

Answer 5

u would add 3 + 18

Answer 6

No..no they are not like terms! you have 3x and 18 so y would just be 18 :)

Answer 7

so the equation is y=3x+18

Answer 8

Yup!

Answer 9

to graph the slope i put the point at 18 for y

Answer 10

(0,18)

Answer 11

ok thanks thats where i was getting confused

Answer 12

You're welcome :)
