Question 443088: Find an equation of the line containing the given pair of points.
(-3,0)and(0,4)
What is the equation of the line?
y=______
(Answer in a slope intercept form. By using integers or fractions for any numbers in the expression.)

You can put this solution on YOUR website!
Find the slope between these two points:
+m+=+%28y%5B2%5D+-+y%5B1%5D%29%2F%28x%5B2%5D-x%5B1%5D%29
+m+=+%284-0%29+%2F+%280+-+%28-3%29%29+=+4%2F3
So our slope is 4/3... Now choose a point.
I'll choose (-3,0). (You can choose either point).
----------------
Now we have a point and a slope... use POINT-SLOPE form!
y-y%5B1%5D+=+m%28x-x%5B1%5D%29
y-0+=+expr%284%2F3%29%28x%2B3%29
highlight%28y=+expr%284%2F3%29x+%2B+4%29
