Answer:
Explanation:
Slope & y-intercept form: y =mx +b
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
