Answer:

slope is 3

Step-by-step explanation:

Slope = $\frac{change in y }{change in x }$

change in y = (13-7), (19-13), (25-19), (31-25)

change in y = 6

Change in x = (4-2), (6-4), (8-6), (10-8)

Change in x = 2

Therefore slope = $\frac{6}{2}$

Slope = 3

What is 2/9 = 4/x+8 i dont get this fraction solving

Dmitriy789 [7]

$\frac{2}{9} = \frac{4}{x + 8} \\$

$\frac{4}{x + 8} = \frac{2}{9} \\$

Inverse both sides

$\frac{x + 8}{4} = \frac{9}{2} \\$

Multiply sides by 4

$4 \times \frac{x + 8}{4} = 4 \times \frac{9}{2} \\$

$x + 8 = 2 \times 9$

$x + 8 = 18$

Subtract sides 8

$x + 8 - 8 = 18 - 8$

$x = 10$

Done...
