Answer:
17
Step-by-step explanation:
rearrange the equation y-17=6x into the format y=mx+c where:
m is the gradient and c is the y intercept
to do this add 17 to both sides:
y=6x+17 you can see now it is in the form y=mx+c
17 is in the place of c so this would be the y-intercept of the line.
hope this helps :)
