Question: y=3×+9

@nswer:

1. y=3×+9= -9
2. y=-2×-7= -2
3. x-y=2
4. ×2-y2

Step-by-step explanation:

1. Looking at y=3x-9 we can see that the equation is in slope-intercept form y=mx%2Bb where the slope is m=3 and the y-intercept is b=-9Since b=-9 this tells us that the y-intercept is .Remember the y-intercept is the point where the graph intersects with the y-axis. So we have one point 0-9
2. =−2−Find solutions on the y=-2×-7=-2
3. carefully and learn how their solutions in image up

This is known as a difference of squares.

4.It can be factored as: x2−y2=(x−y)(x+y)

Explanation:

Notice that when you multiply

(x−y) by

(x+y)

then the terms in

x,y

cancel out, leaving

x2−y2 ...

(x−y)(x+y)

=x2+x,y−yx

−y2

=x2+xy

−xy−y2

=x2−y2
