Add them to cancel y
x+5y=8
<u>2x-5y=1 +</u>
3x+0y=9
3x=9
divide boht isdes by 3
x=3
sub back
x+5y=8
3+5y=8
minus 3
5y=5
divide 5
y=1
(3,1)
Point slope form:
P(x₀,y₀)
slope=m
y-y₀=m(x-x₀)
1)
y-2=-3(x+6)
P(-6,2)
m=-3.
2)
y-5=7(x-14)
P(14,5)
m=7
3)
y+3.7=3.2(x-1.7)
P(1.7 , -3.7)
m=3.2
4)
y+1=11(x-1)
P(1 , -1).
m=11
5)
y+6=-4(x-8)
P(8 , -6)
m=-4
6)
y-7=4(x+3)
P(-3,7)
m=4
