Question

What is the equation of a line, in slope-intercept form, that has a slope of 3 and contains the point (0,5)?

Answer 1

Y=mx+b

That is slope intercept form.
m= slope, which is 3
b= y-int, which is 5.
The y intercept is the value of y/ coordinate where the function intercepts the y axis. The y int is where x=0. In this case, y=5 when x=0.

Then just substitute those numbers into the equation.

y=3x+5
