First write the equation in slope-intercept form which is more commonly known as <em>y = mx + b</em> form where the <em>m </em>or the coefficient of the x term represents the slope of the <em>b</em> or the constant term represents the y-intercept.
Subtract 2x from both sides to get <em>y = -2x - 4</em>.
I put the x term first because that's how it is in y = mx + b form.
Now we can see that the <em>b</em> or the constant term is -4.
We can write this as the ordered pair (0, -4).
Keep in mind when writing a y-intercept as an ordered pair, your x-coordinate will always be 0 in the ordered pair.

I think the answer would be be C.
Answer:
w = 10.4
Step-by-step explanation:
step 1 - You add 16 and 4 which is 20
Step 2 - Than you subtract 20 from both sides so it will be 20 - 20 = 0 and 27.28 - 20 = 7.28
Step 3 - Now you take 7.28 ÷0.7 = 10.4
So the answer is 10.4
