Question

What is the equation in point-slope form of the line passing through (4, 0) and (2, 6)?

y = 4x − 2

y = 2x − 4

y = −3(x − 4)

y = 3(x + 4)

Answer 1

Use the slope formula to find the slope first, what do you get?

Answer 2

idk really

Answer 3

im kinda retarded when it come to math

Answer 4

Slope formula: \(\Large m=\frac{y_{2}-y_{1}}{x_{2}-x_{1}}\)

Answer 5

m=6-0 over 2-4

Answer 6

6 over negative 2?

Answer 7

Yes, which simplifies to -3. :)

Now, do you know how to use the point-slope formula?

Answer 8

but there are 4 answers

Answer 9

so its
y=-3(x-4)?

Answer 10

By process of elimination, that's the only one with a slope of -3, so yea :P

Answer 11

thank you soo much

Answer 12

You're weclome
