We know is a horizontal line, so, if it passes through 1,-5, it also passes through "whatever", -5, like 20, -5 or 1000000, -5, or -100000000, -5 and so on.
so, let's pick another point say -7, -5, check the picture below, and let's check about the equation that runs through it,
Solution
1) Simplify

<span> to </span>


<span>−2= </span>

+

2) Simplify

+

<span>to <span>914</span>
</span>

<span>−2= </span>

3) <span>Add 2 to both sides
</span>

=

<span>+2
</span>
4) Simplify

<span><span>+2</span> to </span>


=

5) <span>Multiply both sides by 7
</span><span>4y= </span>

<span>×7
</span>
6) Simplify

<span><span>×7</span> to </span>


=

7) Simplify

<span> to </span>


=

8) <span>Divide both sides by 4
</span>y=

<span>×4
</span>
9) <span>Simplify <span>2×4</span> to 8
</span><span>y=</span>

<span><span>
Hope this helps

Answer:
I cant see it ill go on your page when you post it with the picture.
I confirm with the answer that k is the slope of the graph<span>. If the variables x and y vary directly when x = 3 and y = 15, then: a. Write an equation that relates x and y.</span>
