Answer:

B (4, 9)

Step-by-step explanation:

Isolate one of the variable on the first equation

5 = -x + y

turn to

x = y - 5

Then insert this into the second equation

3 = 3(y - 5) - y

Simplify-

3 = 3y - 15 - y

3 = 2y - 15

Add 15 to both sides

18 = 2y

Divide by 2

9 = y

knowing y = 9 you can assume that -

(x, 9)

This means the only possible answer is B

Write the equation of the line that includes the point (1,5) and has a slope of 3 in standard form.
Ymorist [56]

Answer:

-3x + y = 2

Step-by-step explanation:

The slope is 3. So the coefficient of x is 3.

when x = 1, y = 5.

So 3*1 + c = 5

So c is 2.

So y = 3x + 2

Therefore, taking 3x to the LHS, we get,

-3x + y = 2

Hope it helps ;)
