Question

How do you find the slope & y-intercept of the equation `3x + 5y = 15`?

Answer 1

Slope is `-3/5` and y-intercept is `3`

Explanation:

`3x+5y=15` [Make y as subject]

`:. 5y=-3x+ 15 or y = -3/5x+3`

Comparing with slope intercept form of straight line `y=mx+c`

we find here slope `m= -3/5` and y-intercept as `c=3`

Therefore , slope is `-3/5` and y-intercept is `3`
