Recall that slope intercept form is written exactly the way it's described: it gives you the slope of the line, then its y-intercept.

So first we can look at the graph, and see that for every 1 unit traveled to the right, the line travels 3 units down. Therefore our slope is -3.

Now we look for the y-intercept - we see the line intersects the y-axis at -3.

So our equation is:

y = -3x - 3

Answer:

rectangle: 2x+2 wide by 2x high

triangle: 2 high

Step-by-step explanation:

Usually, a problem like this is asking you to find dimension expressions that combine to give you the given expression. There are usually a number of possibilities. Using the designators in the attached, we would generally like to have B > C and A about the same as C. That doesn't seem possible with the given factors.

The given quadratic expression factors as ...

area = 4x^2 +6x +2 = (2x+2)(2x +1)

This might be written to match the area formula as ...

(2x +2)(2x +2/2)

This would give A=2, B=2x+2, C=2x, as shown in the attachment.
