Question 1130833: What is the y-intercept and the x-intercept of the line K if the equation is y=2x+1.
My answer was (0,9) but I was wrong for the y-intercept.
My answer was (-8,0) for the x-intercept and I was wrong.
Can you help me and show me where I went wrong? Thanks

Unclear what you did wrong. You need to know something about how to find what you want right.

Equation of line, y=2x%2B1

Find x-intercept:
Set y to 0.
0=2x%2B1
2x=-1
x=-1%2F2
point ( -1/2, 0 )

Find y-intercept:
Set x to 0.

point ( 0, 1 )
