What’s the slope that passes through the points (10,8) and (-15,18)?

slope=-2/5

Step-by-step explanation:

y=18 y0=8 x=-15 x0=10

slope =(y-y0) ➗ (x-x0)

Slope=(18-8) ➗ (-15-10)

Slope=10 ➗ -25

Slope=-10/25

Slope=-2/5

third option: 6x+8

step-by-step explanation:

we can see that the given question is a sum of series and the values of n vary from 0 to 3

the first term will be:

when n=0, [(0)*x+2] => (0+2) => 2

when n=1, [(1)*x+2] => (x+2) => x+2

when n=2, [(2)*x+2] => 2x+2

when n=4, [(3)*x+2] => 3x+2

so adding up all the terms will give us:

=2+x+2+2x+2+3x+2

=x+2x+3x+2+2+2+2

=6x+8

so,

third option is the correct answer ..
