Given the equation y = 5x - 1, what are the intercepts?


x-intercept = -1 and y-intercept =
x-intercept = 1 and y-intercept = -
x-intercept = and y-intercept = -1
x-intercept = - and y-intercept = 1

Answer 1

The intercepts are the points where the line crosses the axes.

At the y-axis, every point has an x-coordinate of 0, so to find the y-intercept, let x = 0 and solve for y.

At the x-axis, every point has a y-coordinate of 0, so to find the x-intercept, let y = 0 and solve for x.

Answer 2

Here's a figure that helps show what I wrote above. This is NOT a graph of your line, so don't conclude anything, as far as values are concerned, from it.
