The y-intercept and x-intercept.

Answer:
y intercept: (0,3)
x intercept (3/7,0)
Step-by-step explanation:
The slope intercept form is y=mx+b, where m represents the slope of a line and b represents the y intercept. This makes the y intercept easy, just (0,3). The x intercept can be found by setting y to 0. Then, you are left with:
0=-7x+3
7x=3
x=3/7
And so the x intercept is (3/7,0). Hope this helps!
