The x-intercept of the graph is (4 , 0)
Step-by-step explanation:
Let us revise the meaning of x-intercept and y-intercept
- x-intercept means value x when y = 0
- That means the graph intersects x-axis at point (a , 0), where a the value of x when y = 0
- y-intercept means value of y when x = 0
- That means the graph intersects y-axis at point (0 , b), where b is the value of y when x = 0
∵ 5x - 4y = 20 is the equation of the graph
- To find x-intercept substitute y by 0
∵ y = 0
∴ 5x - 4(0) = 20
∴ 5x - 0 = 20
∴ 5x = 20
- Divide both sides by 5
∴ x = 4
The x-intercept of the graph is (4 , 0)
