Answers:
(a) 5
(b) (0, 7)
(a) 5
(b) (0, 7)
Explanation:
(a) In the equation y=mx+c, ‘m’ is the gradient. Here m=5.
(b) The y-intercept occurs when x=0. Plugging x=0 into the equation gives y=7, so the point is (0,7).

▶️ Answer/Explanation
Answer: \(\frac{x}{2(x+5)}\) or \(\frac{x}{2x+10}\)
1) Factor numerator: \(x(x-5)\).
2) Factor denominator: \(2(x-5)(x+5)\).
3) Cancel \((x-5)\) terms and simplify.
