Question

Write the equation of a line with an x-intercept of 4 and a y-intercept of -3.

Answer 1

Answer:

y = $\frac{3}{4}$ x - 3

Step-by-step explanation:

Coordinates of x-intercept are (x, 0)

Coordinates of y-intercept are (0, y)

(0, - 3)

(4, 0)  

Slope m = $\frac{3}{4}$

y = $\frac{3}{4}$ x - 3

y = $\frac{3}{4}$ ( - 4) - 3 = - 6

(- 4, - 6)

y = $\frac{3}{4}$ ( - 16) - 3 = - 15

(- 16, - 15)

12 = $\frac{3}{4}$ x - 3

$\frac{3}{4}$ x = 15

x = 20

(20, 12)
