Question

Which of the following equations is of a line whose slope is 3/4 and y-intercept is 6?

A.3x-4y=6
B.3x-4y=6
C.3x-4y=-24
Please help!! :(

Answer 1

C

Explanation:

A line whose slope is 3/4 and y-intercept is 6 will have the equation y = 3/4x + 6. This is in slope intercept form. The answer options are in Standard form/ Convert the equation to this form to find the correct answer.

y = 3/4x + 6

-3/4x + y = 6

Multiply the equation by -4 to clear the fraction and negative.

-4(-3/4x + y = 6)

3x - 4y = -24
