Which number line shows the solution set to this inequality? -2x + 9 < x − 9
kotykmax [81]

Answer:

see below

Step-by-step explanation:

-2x + 9 < x − 9

Add 2x to each side

2x-2x + 9 < 2x+x − 9

9 < 3x-9

Add 9 to each side

9+9 < 3x

18 < 3x

Divide each side  by 3

18/3 < 3x/3

6 < x

What is the slope of the line that passes through the points (2, 3) and (8, 6)? 2/7 2 3/5 1/2
baherus [9]

Answer:

\frac{1}{2}

Step-by-step explanation:

THe slope of a straight line is given by the formula:

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

Where

m is the slope

x_1 and y_1 are the first coordinate pair points [(2,3)]

x_2 and y_2 are the second coordinate pair point [(8,6)]

So, we know that:

x_1 = 2

x_2 = 8

y_1 = 3

y_2 = 6

Now we substitute and find the value of slope to be:

m=\frac{y_2-y_1}{x_2-x_1}\\m=\frac{6-3}{8-2}\\m=\frac{3}{6}\\m=\frac{1}{2}
