Y= 10-5x find the y-intercept. show all work

We can re-arrange it into slope-intercept form().



Switch -5x and 10 around:



Now it's in slope intercept form.



Where is the slope, and is the y-intercept.

So in this case, 10 is the y-intercept.

The y-intercept is the point where the graph of the function crosses the y-axis. That's just another way of saying that it's the value of the function when 'x' is zero (because 'x' is zero at every point on the y-axis). / / / When 'x' is zero, y=10-5x is just y=10 , and there's your y-intercept ... y=10.
