The equation of the line in the slope-intercept form is y = mx + b, where "m" is the slope and "b" is the y-intercept.

"b" is the point (0, yi).

"m" can be found using 2 points P₁ (x₁, y₁) and P₂ (x₂, y₂), according to the formula below:


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

So, to solve this question, follow the steps below.

(a) First graph

Step 01: Find the y-intercept and another point in the graph.

To find the points in the graph, choose a x-value and find its corresponding y-value.

Choosing x = 0, y = 2.

P₁ = (0, 2).

Choosing x = -3, y = -2.

P₂ = (-3, -2).

Step 02:
