The answer is B - vertical angles
Which of the following equations represents a
line that is parallel to the line with equation y=-3x + 4 ?
<u>A. 6x + 2y = 15</u>
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!
