Identifying slope and y intercept of a line

y = 1 - 3x goes to slope -3, y-intercept at 1
x - 3 = y goes to slope 1, y-intercept at -3
y = 3x - 1 goes to slope 3, y-intercept at -1
-x + 3 = y goes to slope -1, y-intercept at 3
Answer:
Step-by-step explanation:
Here, m is the slope and b is the y-intercept
Co efficient of 'x' is the slope and the constant is the y-intercept
Compare the each equation with above form.
y = 1 - 3x ⇒ Slope = -3 & y-intercept = 1
x - 3 = y ⇒ Slope = 1 & y-intercept = -3
y = 3x - 1 ⇒ Slope = 3 & y-intercept = -1
-x + 3 = y ⇒ Slope = -1 & y-intercept = 3
