Question

For the straight line defined by the points (2,55) and (4, 87), determine the slope (m) and y-intercept?

Answer 1

Answer:

Slope(m) = 16

Y intercept (c) = 23

Step-by-step explanation:

Given:

Points : (x1, y1) = (2, 55)

           (x2, y2) = (4, 87)

Using two point form to calculate slope:

$m = \frac{y2-y1}{x2-x1}$

$m = \frac{87-55}{4-2}$

      m = 16

To find y intercept:

Take any one point ans slope :

Using slope point formula:

y = mx + c

87 = 16(4) + c

Solving for c:

c = 23
