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:

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
