. Find the slope of the line containing the points (3,-7) and (4,-9).
Neko [114]

Answer:

m=-2

Step-by-step explanation:

the formula for slope (m) is (y2-y1)/(x2-x1)

the given points are (3,-7) and (4,-9)

label the points;

x1=3

y1=-7

x2=4

y2=-9

substitute into the equation:

m=(-9--7)/(4-3)

m=(-9+7)/(1)

m=-2/1

the slope is -2

hope this helps!

Find the slope and the y-intercept of 3x-6y=48
Sedaia [141]

Answer:

Step-by-step explanation:

3x-6y=48

Turn the equation into slope intercept form (y=mx+b)

x-2y=16 (Subtract x)

-2y=16-x (Divide by -1/2)

y=1/2x-8

The y-intercept is b, so -8 is the y-intercept.

The slope is m, so the slope is 1/2.
