Answer:
The first option
Step-by-step explanation:
The slope m can be calculated using the slope formula
m = (y₂ - y₁ ) / (x₂ - x₁ )
with (x₁, y₁ ) = (0, - 2) and (x₂, y₂ ) = (3, 0) ← 2 points on the line
m = =
The y- intercept is the point on the y- axis where the line crosses, that is - 2
Thus slope = and the y- intercept is - 2
