What are the (y)-intercept and slope in (10x+4y-44=0)?

Answer and explanation

Correct answer: (y)-intercept (11), slope (-\frac{5}{2})

The direct answer is option A: y-intercept 11 and slope \(-\frac{5}{2}\). First isolate y: \(10x+4y-44=0\). Move the x-term and constant: \(4y=-10x+44\). Divide every term by 4: \(y=-\frac{10}{4}x+\frac{44}{4}=-\frac{5}{2}x+11\). Comparing with \(y=mx+c\), the slope is \(m=-\frac{5}{2}\) and the y-intercept is \(c=11\). Option A is correct. Option B has both signs reversed. Option C treats original coefficients as the answer and misses the required rearrangement. Option D incorrectly swaps the coefficients and does not give slope-intercept form. A y-intercept is the value of y when x is zero; here it is 11. Memory cue: rewrite as \(y=mx+c\); the coefficient of x is slope and the constant is the y-intercept.
