B + 7.5 = 4.8
     -7.5   -7.5
-----------------------
         b  =   -2.7

Hope this helps!!!!!




You can also check your answer by doing replacing the number with the variable ( don't just write the anwser just because you know it, since its pre algebra you have to do it algebraically like above)

-2.7 + 7.5 = 4.8

Hope it helps!

Determine the slope of the line that has the following coordinates: (5, 9)(11, - 3)
AlladinOne [14]

Answer:

x_1 = 5, x_2 =11, y_1 =9, y_2 = -3

The slope can be founded with this formula:

m =\frac{y_2 -y_1}{x_2 -x_1}

And replacing we got:

m =\frac{-3 -9}{11-5}= -2

And the best answer for this case would be :

m=-2

Step-by-step explanation:

For this case we have the following two points given:

x_1 = 5, x_2 =11, y_1 =9, y_2 = -3

The slope can be founded with this formula:

m =\frac{y_2 -y_1}{x_2 -x_1}

And replacing we got:

m =\frac{-3 -9}{11-5}= -2

And the best answer for this case would be :

m=-2
