Find the slope, vertical intercept and horizontal intercept of (2,9) and (4,3)

M = - 3

Step-by-step explanation:

Find the Slope:

Slope is equal to the change in  y  over the change in  x

, or rise over run.

m  =  

The change in  x  is equal to the difference in x-coordinates (also called run), and the change in  y  is equal to the difference in y-coordinates (also called rise).

m =

Substitute in the values of  x  and  y  into the equation to find the slope.

m =

Simplify.

m =

m = -3

according to the triangle sum theorem, all the angles in a triangle must add up to 180 degrees. if we know one angle is already 90, we do 180-90=90. the other 2 angles must add up to 90, exactly.

step-by-step explanation:

-22

times both sides by 2, times () by 8, add alile terms, move terms, add alike and caculate divide both sides by 3
