Question

Write an equation of the line through (–4, 4) and (8, 8) in point-slope form.

Answer 1

Hint: Use the slope formula to find the slope of the line.

Answer 2

Sorry my computer has been lagging badly

Answer 3

nah its cool

Answer 4

the slope is 1/3 where do i go from here?

Answer 5

@jim_thompson5910 do you know?

Answer 6

Now you use this formula

\( y - y_1 = m(x - x_1)\)

substitute m = 1/3, y_1 = 4, x_1 = -4

Answer 7

Then isolate y afterwards and simplify

Answer 8

is y-4=1/3(x-4) the right answer

Answer 9

is y isolated?

Answer 10

Don't you have to add 4 to both sides to isolate y?
Then afterwards, it still must be in the form y = mx + b because that's the point slope form.

Answer 11

wait so what answer did u get cuz none of the multiple choice answers look like that

Answer 12

please help @Hero
