You can put this solution on YOUR website!
Each x is 1 more than the value above it.
Each y is 11 more than the value above it.
The slope of that linear function is 11,
because that is how much y increases as x increases by 1.
So the equation is
y=11x%2Bb and we just have to find b , the y-intercept.
The minus sign in y =___x – ___ is already hinting that b is negative.
WE can use any (x,y) from the table to substitute into y=11x%2Bb and find b .
For example, using (1,1) , x=1 and y=1, and we get
1=11%2A1%2Bb
1=11%2Bb
b=11-1
b=-10
So the equation is highlight%28y=11x-10%29
