Given equation
Combine like terms
Addition or subtraction property of like terms
Multiplication or division of property of equality
Addition or subtraction property of like terms
And then your answer or (given equation I’m assuming
Substitute everything in first
3(-2)-1-3(-2)
Then simplify
-6-1+6 = -1
The answer is -1
(22 - 3) / (4 +1) = 19/5
slope = 19/5
r is the x coordinate and s is the y coordinate. Positive slopes go from lower left to upper right, like going up stairs or up a hill. The line that goes through (r, s) that is positive is line B.
