PLEASE ANSWER QUICKLY AND CORRECTLY I APPRECIATE IT SO MUCH !!! :)))


Is (-1,4) a solution to the graph of

y= 3x + 7?

EXPLAIN WHY OR WHY NOT

Respuesta :

vialia

Answer:

True

Step-by-step explanation:

(-1,4) = (x,y)

This means if "x = -1, then y should be 4"

y = 3x + 7

y = 3(-1) + 7

y = -3 + 7

y = 4

It is saying if x is -1, y is 4. This statement of "Is (-1,4) a solution to the graph of "y = 3x + 7?" Is true. You can also graph this and find the point (-1,4) and it would be on the line.

:D Hope it Helps (I dunno why I put it on this answer box now)

Answer:

Yes.

Step-by-step 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.
