Question

The x-intercept of a positively-sloped line is -5, and the area of the triangle formed by the line, the x-axis, and the y-axis is 10. What is the slope of the line?

Answer 1

Answer:

The coordinates of the first point are since the x-coordinate is and (−4, 0), −4 the y-coordinate of every point on the x-axis is 0. For the second point, the mid-point of the line segment is halfway between the endpoints and (2, 9) (2, 0). Thus, the midpoint has x-coordinate 2 and y-coordinate

9292 the number halfway between 9 and 0. Based on the coordinates (−4, 0) and (2,92)(2,92), the slope of line k is

92−0/2−(−4)92−0/2−(−4)

=92/6=92/6=34
