Question

P(-2,-1) m=2
write an equation of a line

Answer 1

so our form is y = mx+b
we know that m =2
so we have
y = 2x+b
now we want to find what b is
so we sub in our point for x and y
let x = -2 and let y = -1
y=2x+b becomes
-1=2(-2)+b
can you solve for b?

Answer 2

b would = 3
-1=2(-2)+b
-1=-4+b
3=b

Answer 3

yep

Answer 4

y = 2x+3

Answer 5

okay thank you
