To find the slope, use the S=(y2 - y1)/(x2 - x1) formula

S=(18-4)/(7-0)

S=14/7

S=2

After finding the slope, us the intercept formula to find the intercept

m is the slope

y-y1=m(x-x1)

y-4=2(x-0)

y=2x+4

Answer:

Answer: The slope is 2. The y-intercept is 4 which means point (0, 4).

Explanation:

First, find the slope of the line that passes through those two points using the slope formula.


slope = m = (y_2 - y_1)/(x_2 - x_1)

where the points are
(x_1, y_1) and
(x_2, y_2)


slope = m = (18 - 4)/(7 - 0) = (14)/(7) = 2

The slope is 2.

One of the given points is (0, 4). Since the y-intercept lies on the y-axis, the x-coordinate of the y-intercept is 0. Point (0, 4) is the actual y-intercept.

Answer: The slope is 2. The y-intercept is 4, or point (0, 4).
