Answer:

–6x + 2y = 3/2 is Sandra's equation.  

Step-by-step explanation:

Given Equation of Tomas is

y=3x+\frac{3}{4}

Solution of equation of Sandra is same as solution of Tomas Equation.

This only possible when ratio of the coefficients of the variable and constant term is equal.

So,

Multiply Tomas equation with 2.

2y= 6x + 3/2

This is one of the equation possible for Sandra's equation

Therefore, –6x + 2y = 3/2 is Sandra's equation.

Pick the correct answer <br> Please help thanks :)
meriva

Answer:

B

Step-by-step explanation:

First create the equation that has slope of -1 in the form of y=mx+b. Because the slope is -1, m=-1, so the equation is y=-x+b. Now we see that we are given the point (-3, 8) as an intersection point. Substitute x and y for -3 and 8 in our equation. With this information, our equation becomes 8=3+b. Solving, b=5. Our equation is now y=-x+5.

Simplifying all of the answer choices, we have

A. y=-x-5

B. y=-x+5

C. y=-x-5

D. and E. as what they already show

The only answer that matches is B.
