Question

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

Answer 1

Answer:

              $\bold{y=-\frac12x}$

Step-by-step 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:

$m=\dfrac{-1-0}{2-0}=-\dfrac12$

Therefore the equation:

                                        $y=-\frac12x+0\\\\y=-\frac12x$
