Answer:

To graph the equation, you need to find the slope and y-intercept.

y = mx + b

[slope-intercept formula; m is the slope, and b is the y-intercept]

y = 4x + −1

[given equation before being simplified]

y = 4x − 1

[given equation]

m = 4

b = (0, −1)

Proof:

m =
(rise)/(run) =
(y_2 - y_1)/(x_2 - x_1)

x₁ = 0

x₂ = 1

y₁ = −1

y₂ = 3

m =
(3 - -1)/(1 - 0)

m = 4

b = (0, −1)

[the value for x₁ and y₁ equals the y-intercept: (0, 1)]

Graph:
