What is the answer for No.22 &amp; 23 please
kondor19780726 [428]
Hello!

<u>Number 22</u>: We'd plot the first point at 0 since there is no stated y-intercept. Next, we'd use our slope to determine where to plot the next point, and that would create our line. According to the problem, our slope is -\frac{1}{2}, which automatically tells us that the slope would be going downwards because it's negative. 

To plot our point, use the slope while going down and across from our y-intercept, which is 0. Go down 1, and over 2.

Your points should be at (0, 0) and (-1, 2)


<u /><u>Number 23:</u> This one will be a bit trickier since the equation is not in slope-intercept form. First, let's convert it to slope-intercept form. 

-2x + 3y = 6&#10;&#10;-2x + 2x + 3y = 6 + 2x&#10;&#10;3y = 6 + 2x&#10;&#10;3y/3y = 6/3y + 2x/3y&#10;&#10;y = 2 + 2/3x

Flip some of those numbers around to get our equation in slope-intercept form:

y =  \frac{2}{3}x  + 2

Now to graph this, we do the same as we did for the last problem. Plot our first point at (0, 2), since 2 is our y-intercept. Afterwards, go up 2 and over 3, then plot the other point.

Your points should be at (0, 2) and (4, 3)

The diagonal of a square is x units. What is the area of the square in terms of x? square units square units 2x square units squ
STatiana [176]

For this case we have that by definition, if we draw the diagonal of a square two rectangular triangles are formed. If the diagonal measures "x", then the Pythagorean theorem is fulfilled:

l ^ 2 + l ^ 2 = x ^ 2

Where:

l: It's the side of the square.

2l ^ 2 = x ^ 2\\l ^ 2 = \frac {x ^ 2} {2}

We know that the area of a square is given by:

A = l ^ 2

So, the area is:

A = \frac {x ^ 2} {2}

Answer:

A = \frac {x ^ 2} {2}
