What is the y intercept of y=6x+3

y = 6 x − 3

Step-by-step explanation:

The slope-intercept form is  y = m x + b , where  m  is the slope and  b  is the y-intercept.

y = m x + b

Using the slope-intercept form, the y-intercept is  − 3 .

b = − 3

-3

Explanation:

I remember the formula to be y=mx+b, and mx representing the slope times x.  Therefore, b would equal the y-intercept, or in this case 3.  Using slope intercept form, you get -3.    

the answer is b.
