How do i graph y=-x+3
Galina-37 [17]

Answer:

y=-x+3 follows the same equation as y=mx+b

3 is b, and b is the y-intercept. The y intercept is where the line crosses on the y axis,  and -x is is m, which is the slope. However since its a variable, its point is on the same number as positive three on the y axis, so then its 3 on the x axis.

Step-by-step explanation:

Can someone find and explain the answer to me!
tia_tia [17]
<h3>Answer:  6m</h3>

12m can be written as 6m*2

18m^2 can be written as 6m*3m

Both factorizations have '6m' in them, which shows we have a common factor. This is the greatest common factor as we cannot pull anything further out, ie, 2 and 3m have nothing in common other than 1.

The points (4,k) and (5,-8) fall on a line with a slope of -7. what is the value of k?
babunello [35]

Answer:

k= -1

Step-by-step explanation:

To find k, use the points and the m =-7 in the slope formula:

m=\frac{y_2-y_1}{x_2-x_1}\\\\-7=\frac{-8-k}{5-4} \\\\-7 = \frac{-8-k}{1}\\\\-7=-8-k\\\\k = -8+7\\\\k=-1
