Question

please help......the x-intercept of a line is (3/2,0) and the line slope =4, what is the equation of the line in slope-intercept form?

Answer 1

y = mx + b is the general slope intercept form.
Slope m = 4
y = 4x + b
Point (3/2, 0) is on the line. Put x = 3/2, y = 0 and solve for b.

Answer 2

so 0=4(3/2)+b?

Answer 3

i got -6

Answer 4

Yes. Put b back in y = 4x + b and you will have your answer.

Answer 5

so ill put -6?

Answer 6

where b is?

Answer 7

Put b = -6 in y = 4x + b.

Answer 8

and that would be the answer

Answer 9

Yes. y = 4x - 6 is the equation of the line in slope-intercept form.
