Question

Which equation shows a slope of 3 and a y-intercept of (0,7)?

y = 7x + 3

y = −7x + 3

y = 3x − 7

y = 3x + 7

Answer 1

y=3x+7
slope is always the number by x
intercept is always the b in the equation

Answer 2

`y=3x+7`

Explanation:

If the equation for a line in y-intercept form is:

`y=mx+b`

Where m=slope, and b=y-intercept, then you just compare with your parameters.

If m=3 and b=7, then the correct answer is
`y=3x+7`

Please let me know if you have any other questions about this or anything else.

Thanks!
