find the x - intercept of the line 7x + 4y = 28. write your answer as an integer or as a simplified proper or improper fraction, not as an ordered pair.
Answer
Explanation:
Step1: Set y = 0 for x - intercept
When finding the x - intercept of a line, we set (y = 0) in the equation of the line. So the equation (7x+4y = 28) becomes (7x+4\times0 = 28).
Step2: Solve for x
We have (7x=28). Divide both sides of the equation by 7: (x=\frac{28}{7}).
Step3: Simplify the result
(\frac{28}{7}=4).
Answer:
4
