Answer:
Yes.
Explanation:
Note that the point:
(x , y) = (-1 , 4)
x = -1
y = 4
Plug in the corresponding numbers for the corresponding variables in the given equation:
y = 3x + 7
(4) = 3(-1) + 7
Remember to follow PEMDAS. PEMDAS is the order of operation, and stands for:
Parenthesis, Exponent (& Roots), Multiplication, Division, Addition, Subtraction.
First, multiply 3 with -1:
4 = (3 * -1) + 7
4 = -3 + 7
Next, simplify by adding -3 with 7:
4 = (-3 + 7)
4 = 4
Yes. (-1 , 4) is a solution for y = 3x + 7, as the two sides of the equation equal.
