You can put this solution on YOUR website!
This seems hard.
You should have a tutor look at that.
Ooh, go on this website called Algebra.com, and ask this question !
Hope I helped (:

slope intercept form equation is when given these points : (-4 , 1) , (0 , 16)
--------------
y = mx + b
------
slope = (16-1)/(0--4) = 15/4 =
-----
y- intercept: f(0) = 16
----------------------
Equation:
y = (15/4)x + 16

+%28+y+-+1+%29+%2F+%28+x+-%28-4%29+%29+=+%28+16+-+1+%29+%2F+%28+0+-%28-4%29+%29+
+%28+y+-+1+%29+%2F+%28+x+%2B+4+%29+=+15+%2F+4+
Multiply both sides by +4%2A%28+x%2B4+%29+
+4%2A%28+y+-+1%29+=+15%2A%28+x+%2B+4+%29+
+4y+-+4+=+15x+%2B+60+
+4y+=+15x+%2B+64+
+y+=+%28+15%2F4+%29%2Ax+%2B+16+
check:
( -4,1 )
+y+=+%28+15%2F4+%29%2Ax+%2B+16+
+1+=+%28+15%2F4+%29%2A%28-4%29+%2B+16+
+1+=+-15+%2B+16+
+1+=+1+
( 0,16 )
+y+=+%28+15%2F4+%29%2Ax+%2B+16+
+16+=+%28+15%2F4+%29%2A0+%2B+16+
+16+=+16+
OK
