Answer:
Slope intercept form is y=mx+b
m= the slope
b= the y intercept
so basically if I had a slope of 3/1 and a y intercept of 7 and I wanted to write it in slope intercept form I would put:
y=3x+7
if your y intercept is a negative, you would just put -b instead of +b
If you wanted to graph it:
-slope is the rise over run
-y intercept is where a line meets the y axis
