Question 232024
we will solve number one by substitution
x-y=2, same as x=y+2
x+2y=5
substitute the first equation into the second
y+2+2y=5
subtract 2
3y=3
y=1
-------------------------------
work the first equation using y=1
x-1=2
add 1
x=3
ordered pair
(3,1)point of intersection of the two equations
------------------------
use y=mx+b for the other points
example
x+2y=5
2y=-x+5
y=-1/2+5/2
m=slope
b=y int
Give the others a try.
