11

the y intercept is -13

Step-by-step explanation:

First of all we need the line equation so let's find it first :

y = mx + b

y = 2x + b

The line passes through point ( 8 , 3 ) which means if put 8 instead of x the y must equals to 3 :

2(8) + b = 3

16 + b = 3

b = 3 - 16

b = - 13

Now we have the equation of the line :

y = 2x - 13

To find the y-intercept we just need to out 0 (zero ) instead of x ; Let's do it :

y = 2(0) - 13

y = 0 - 13

y = - 13

Thus the y-intercept = - 13

correct me if i'm wrong and if it is i'm truly sorry.

step-by-step explanation:

because where the point where the 2 lines intersect is (3,-1) the x value is 3
