PLEASE help me!!

A line has a slope of and a y-intercept of 5. Write the equation of the line in slope-intercept, form and explain how you would use the slope and y-intercept to graph the equation.

y = m x + b

m is the slope
b is the y axis intercept.
line has slope m, which you did not write, and goes through ( 0 , 5 )
if you go right one and up m from that point, you get a second point. Draw a line through those two points.
