Question:

Find the equation of a line if its x-intercept is 5 and y intercept is 4.

a 4x + 5y = 20 → answer

b 5x + 4y = 20

c 4x - 5y = 20

d 4x - 5y = -20

Solution:

x intercept = 5

y intercept = 4

line passes through (5, 0) and (0, 4)

m = (y2-y1) / (x2 - x1)

m = (4 - 0) / (0 - 5)

m = - 4/5

y - y1 = m(x - x1)

y - 0 = -4/5(x - 5)

y = -4x/5 + 4

5y = -4x +20

5y +4x = 20

4x + 5y = 20

Answer:

The equation of a line if its x-intercept is 5 and y intercept is 4 is 4x + 5y = 20
