Answer:
-4x - 3 = -8
Step-by-step explanation:
On our left, we have -x in 4 places = 4(-x) = -4x
And on the left, we also have -1 in 3 places = 3(-1) = -3
Altogether in our left, we have: -4x +(-3)
That is: -4x - 3
On our right, we have -1 in 8 places, which is 8(-1) = -8
Therefore, the equation that represents the model would be:
-4x - 3 = -8
We can employ some logic to reduce the answers we need to test. We know that the slope perpendicular to line l has to have a negative reciprocal slope, so a slope of
. We see that in A and C, as x increases so does y. That means the slope of these equations are positive, which we don't want. Now for some algebra:
We se that D has the correct slope so that must be the answer.
Answer:
A reflection over the <em>y</em>-axis.
The value of x=1
Step-by-step explanation:
Given the equations as :
-2x + y= 8
5x - y= -5 ------adding the equations
---------------------
3x = 3 -------dividing both sides by 3
x = 1

- The y-intercept is the y value when x = 0. Another way to reword that is when the graph crosses the y-axis.
Step-by-step explanation:
According to the graph, the line passes the y-axis at y = 4. Therefore, our y-intercept is (0, 4).
