Question

What is the equation of the line in slope-intercept form?

Answer 1

`\bold{y=-\frac12x}`

Explanation:

Slope-intercept form: y = mx + b

The line intersect Y-axis at y=0 so b = 0

The line passses through points (0, 0) and (2, -1), so the slope:

`m=(-1-0)/(2-0)=-\frac12`

Therefore the equation:

`y=-\frac12x+0\\\\y=-\frac12x`
