They way to find the y-intercept from two points is to first find the slope, which can be derived from the formula
.
Then, you can plug in one of the two points
or
into the formula y=mx+b to solve for b, which is your y-intercept.
Remember, you can do anything to an equiton as long as you do it to both sides
-(7-4x)=9
we can either distribute to get -7+4x=9 or multiply both sides by -1 to get
7-4x=-9
then minus 7 both sides
-4x=-16
divide by -4 both sides
x=4

4 9/10 + 3 7/10
49/10 + 37/10(turned into an improper fraction
86/10 ( both figures added )
=8 6/10(result)
