To Match
To isolate -1 we need to subtract 2m from both sides
2m - 1 = 3m (SUBTRACT 2m)
To isolate 1 we need to subtract m from both sides
2m = 1 + m (SUBTRACT m)
To isolate m we need to add 1 from both sides
m - 1 = 2 (ADD 1)
To isolate m we need to subtract 2 from both sides
2 + m = 3 (SUBTRACT 2)
To isolate m we need to add 2 from both sides
-2 + m = 1 (ADD 2)
To isolate m we need to subtract 1 from both sides
3 = 1 + m (SUBTRACT 1)

A wright a system of equation to describe the situation
Answer:
The slope line will change from negative to positive.
To solve this you must replace x with -4 and y with 5 in the equation 7x + y² like so:
7 × (-4) + 5²
To solve this use PEMDAS (Parentheses, Exponent, Multiplication, Division, Addition, Subtraction)
REMEMBER: IF NOT APPLICABLE TO THE EQUATION YOU MAY SKIP THAT STEP IN PEMDAS .
Exponent...
7 × (-4) + 5²
5² = 5 × 5 = 25
7 × (-4) + 25
Multiplication...
7 × (-4) + 25
7 × (-4) = -28
-28 + 25
Addition...
When adding a positive number with a negative number you will act as if you are subtracting the two numbers, then take the sign of the largest number (disregarding the signs). In this case the largest number is 28 and its sign is negative. Your answer will have a negative sign.
-28 + 25 = -3
-3
Hope this helped!
