When you are given a point (x1,y1) and slope m the equation is
y-y1=m(x-x1)
given
slope=7
(x,y)
(3,22)
x1=3
y1=22
y-22=7(x-3) is the equation or
y=7x+1
4 bc you can make 1/2 into 2/4 and they would all have a denominator of 4
<span>A. x^2+y^2-8x-4y+11=0
It is a circle
</span>
3(2x+1)=15
6x+3=15
-3 -3
6x=12
divide each side by 6
x=2
