Determine the equation of the line for the given information: Two points on the line are (0, 4) and (7, 18). Use the points to first determine the slope and y-intercept. Then write the equation of the line.

Answer:

Slope = 2

Y-intercept = 4

Step-by-step explanation:

Slope (m):

m = (y2 - y1) / (x2 - x1) = (18 - 4) / (7 - 0) = 14 / 7 = 2

Y-intercept:

To find the y-intercept, all you have to find is a coordinate that shows x as zero. This will put the line directly on the y axis - giving you the y-intercept.

In this case, the point is (0, 4), which tells us that the y-intercept is 4.
