Question
What is the x-intercept of the graph of 8x + 6y = 24 in the xy-plane?
- (3,0)
- (4,0)
- (6,0)
- (8,0)
The correct answer is: (3,0)
HINT : x - intercept lies in the form of (a,0)( is the point where line cuts the x-axis)
and satisfies the given equation.
Explanation
x- intercept lies in the form of (a,0) and satisfies the given equation
Step 1: substitute a,0 in the given equation 8x + 6y =24
8 
a + 6 0 = 24
8 a = 24
a = 
= 3
∴ a = 3
∴ x-intercept (a,0) = (3,0)
