Question

Write the equation of the line passing through the points (0, 0), (2, 1), and (-2, − 1).​

Answer 1

y = 0.5x

Explanation:

Slope = m = (2-0)/(1-0) = 1/2 or 0.5

y-intercept = b = 0 since it passes through (0,0)

Slope-Intercept form of a line is y = mx + b

So the equation is
y = 0.5x + 0

or

y = 0.5x
