Your y-intercept (other wise known as b) is going to be -5. As for your slope it will be 3/1 or also 3.

<u>So your equation will be y = 3x - 5 </u>

So this is using slope-intercept form (y=mx+b)

m is slope and b is the y-intercept

Looking at the graph, the line goes through the y-axis at (0,-5) so -5 is your y-intercept.

The slope of the line can be determine by using "rise over run". Find two points on the graph (I used 0,-5 and 1, -2). Count up from -5 to -2 (you get 3), count over from 0 to 1 (you get 1). Rise over run means that the slope equals 3.

Now, you just have to plug the numbers in.

Slope = 3; y-intercept = -5

y = 3x -5

The answer is A.) Y= 3x - 5

Hope this helps. Lmk if you need any more help :)

Answer:

In the case of the second frame, the sides are not perpendicular to each other.

Step-by-step explanation:

A. The length (l) of the frame is 20 and width (w) is 15.

If the frame is a rectangular one, then diagonal (d) can be calculated from the Pythagoras Theorem as $d^{2} = l^{2} + w^{2} = 20^{2} + 15^{2} = 625 = 25^{2}$

⇒ d = 25 (Also given)

So, the frame is rectangular one.

B. The length (l) of the frame is 22 and width (w) is 10.

If the frame is a rectangular one, then diagonal (d) can be calculated from the Pythagoras Theorem as $d^{2} = l^{2} + w^{2} = 22^{2} + 10^{2} = 584$

⇒ d = 24.166 ≠ 24 (24 is the given value)

So, the frame is not a rectangular one.

C. The length (l) of the frame is 21 and width (w) is 20.

If the frame is a rectangular one, then diagonal (d) can be calculated from the Pythagoras Theorem as $d^{2} = l^{2} + w^{2} = 21^{2} + 20^{2} = 841 = 29^{2}$
