Question

Find the equation for the line with the given properties. x-intercept=2 y-intercept=-1

Answer 1

If the y intercept is =-1, that's where the line goes through the y axis; that is a point on your line. If the other place it goes through is the x axis at 2, that is another point on your line. From there you find the slope of the line and then write the equation in slope intercept form. Here, like this:

Answer 2

That gives us a slope of 1/2. Use that as the "m" in your slope-intercept formula, y = mx + b.
