Answer:

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

y = mx + b

⬑<em>[slope-intercept formula; m is the slope, and b is the y-intercept]</em>

y = 4x + −1

⬑<em>[given equation before being simplified]</em>

y = 4x − 1

⬑<em>[given equation]</em>

║m = 4

║b = (0, −1)

Proof:

m = \frac{rise}{run} = \frac{y_2 - y_1}{x_2 - x_1}

x₁ = 0

x₂ = 1

y₁ = −1

y₂ = 3

m = \frac{3 - -1}{1 - 0}

║m = 4

║b = (0, −1)

<em>[the value for x₁ and y₁ equals the </em><em>y-intercept: (0, </em>−<em>1)</em><em>]</em>
