Question

What is the slope of the line with an x-intercept of 4 and a y-intercept of -3?

Answer 1

Answer:

The x intercept is the point where the line crosses the x axis. At this point y= 0. Given x- intercept = 4, then if we consider points x1, y1 , their ordered pair is (4,0) Since x intercept is 4 and y=0. y- intercept is -3, similarly at this point, we get x=0, The ordered pair of x2, y2 is(0,-3).Now, we got x1,y1= (4,0) and x2,y2=(0,-3), Hence their slope (m) = y2-y1/ x2-x1 ( according to formula). i.e m= -3-0/0-4= m= -3/-4, m= 3/4. Hence the slope of the line is 3/4. Hope this helps you.
