Question

Identifying Slope and y-Intercept of a Line

Identify the slope and y-intercept of each linear function's equation
y = 1 - 3x
slope = 3 y-intercept at -1
y = 3x - 1
slope = -1 y-intercept at 3
X-3 = y
slope = -3; z-intercept at 1
--> + 3 = y
slope = 1:y-intercept at -3

Answer 1

Explanation:

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

y = mx + b

m - slope

b - y-intercept

y = 1 - 3x = -3x + 1

slope = -3

y-intercept at 1

y = 3x - 1

slope = 3

y-intercept at -1

x - 3 = y → y = 1x - 3

slope = 1

y-intercept at -3

x + 3 = y → y = 1x + 3

slope = 1

y-intercept at 3
