Question

Write the slope-intercept form of the equation of the line that passes through (4, 2) with a slope of 3.
a. y = 3x - 10
b. y = 3x + 4
c. y - 2 = 3 (x - 4)
d. y = 4x + 3

Answer 1

Okay.

So the formula template is:
\[y = mx + b\]

Now m is slope and b is the y intercept.

Now just plug in everything.

Answer 3

Thank's for the help! :)
so it would be y=3x+4?

Answer 4

@annjewell1998 No, y=3x+4 is incorrect.

Answer 5

@annjewell1998 Both b and d are incorrect, because none of them pass through the points (4, 2)

Answer 6

So is it a then?

Answer 7

@annjewell1998 Hold on

Answer 8

@annjewell1998 That's strange, both a and c are the same thing.

Answer 9

@annjewell1998 Oh, the question says

Write the slope-intercept form

A is the slope intercept form of C. So yeah, the answer to this would be A. :)

Answer 10

Thank you!!

Answer 11

@annjewell1998 Yeah, no problem. :)
