Q# ..7 match the equation with its graph -4x - 2y =8
1 answer:
If you divide by 8, you can put the equation into intercept form. That form is ...
... x/a + y/b = 1
where <em>a</em> and <em>b</em> are the x- and y-intercepts, respectively.
Here, your equation would be
... x/(-2) + y/(-4) = 0
The graph with those intercepts is not shown with your problem statement here. See the attachment for the graph.

Answer:
27
Question:
Find so that
is a solution to
.
Step-by-step explanation:
So we are asked to replace with -14 and solve for
in the equation:
.
with
:
Add 42 on both sides:
Divide both sides by 2:
.
So the -coordinate that corresponding to
is
.
Verify that:
is a point satisfying
.
Replace with 27 and
with -14:
is true so our work must be right.
