Question

Identify the slope and y-intercept of each linear function's equation.

---2+3=y
slope = 1, y-intercept at -3
X-3=y
slope = -3; y-intercept at 1
y = 3r - 1
slope = 3; y-intercept at -1
y = 1 - 3x
slope = -1; y-intercept at 3

Answer 1

- x + 3 = y ....... slope = -1 and y-intercept of 3

x - 3 = y ......... slope = 1 and y-intercept of -3

y = 3 x - 1 ......... slope = 3 and y-intercept of -1

y = 1 - 3 x ....... slope = -3 and y-intercept of 1

Explanation:

Just read the slope and y intercept from the equations since they are all given in slope-intercept form:

- x + 3 = y ....... slope = -1 and y-intercept of 3

x - 3 = y ......... slope = 1 and y-intercept of -3

y = 3 x - 1 ......... slope = 3 and y-intercept of -1

y = 1 - 3 x ....... slope = -3 and y-intercept of 1
