Question

Help please for equation that represents the line that passes through the point (-2, 6) and has a slope of 4?

Answer 1

Start with

y = mx+b

where m is the slope and b is the y-intercept

Answer 2

You're given a slope of 4. So m = 4

One point that lies on the line is (-2,6). So x = -2 and y = 6

So

y = mx+b

becomes

6 = (4)(-2)+b


Now solve for b

Answer 3

How do I do that....

Answer 4

6 = (4)(-2)+b

will become

6 = -8+b

what's next?

Answer 5

@jim_thompson5910 do I subtract 8?

Answer 6

6 = -8+b

is the same as

6 = b-8

so what's next?

Answer 7

divide?

Answer 8

add 8 to both sides

Answer 9

so 14 = b :D

Answer 10

yes, which means that

y = mx+b

becomes

y = 4x+14

Answer 11

since m = 4 and b = 14

Answer 12

Oh okay thanks
