Help pls, it’s about finding the y-intercept.

-2

Step-by-step explanation: the y intercept is -2 because on the table x is at -2 and y is at 0 making that the origin for Y and the -2 according to graphs would intercept the origin. Thus making -2 the intercepting value for (Y)

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 ..

x+y=90

x=30-y=x

step-by-step explanation:

if you understand you will get the answer
