Question

Find the equation of the line. Use exact numbers.

Y= ___x + ___

Answer 1

y = 3x + 3

Explanation:

The graph passes through the points (-1, 0) and (0, 3).

Slope = m = Δy/Δx = (y₂ - ₁)/(x₂ - x₁) = (3 - 0)/(0 - (-1)) = 3/1 = 3.

The y-intercept (b) is at y = 3.

The equation for a straight line is

y = mx + b

Thus, the equation for your line is

y = 3x + 3
