Answer:
C the coordinates are just fliped since It was flipped on the y- axis
Step-by-step explanation:
Answer:
y = -6x + 31
Step-by-step explanation:
In order for us to make this an equation of the form y = mx + b we have to find the slope.
The formula for slope is rise/ run. The rise is 6 and the run is -1.
So, the slope is 6/-1 or -6.
Our equation is now: y = -6x + b
Substituting 4,7 into the equation we get 7 = -24 + b
So, b = 31.
To check out answers we substitute 5,1 in and it works.
<h3>Given</h3>
z = 3
2y +z = 1
2x +3y +2z = 13
<h3>Find</h3>
x, y, z
<h3>Solution</h3>
... z = 3 is given
Substitute that into the second equation.
... 2y + 3 = 1
... 2y = -2 . . . . . subtract 3
... y = -1 . . . . . . . divide by the coefficient of y
Substitute these two solutions into the third equation.
... 2x +3(-1) +2(3) = 13
... 2x = 10 . . . . . . . . . . . . collect terms, subtract 3
... x = 5 . . . . . . . . . . . . . . divide by the coefficient of x
The variable values are: x = 5, y = -1, z = 3
The answer is y=-3 hope it helps
