Question

Using the slope and the y-intercept graph the line represents by the following equation then select the correct graph 2y + 4 =0

Answer 1

Explanation:

2y + 4 = 0 subtract 4 from both sides

2y = -4 divide both sides by 2

y = -2

The slope-intercept form of an equation of a line:

y = mx + b

m - slope

b - y-intercept → (0, b)

In the equation

y = -2

slope: m = 0

y-intercept: b = -2 → (0, -2)

y = -2 - it's a horizontal line
