Answer:
slope = , y- intercept = - 1
Step-by-step explanation:
to calculate the slope m use the gradient formula
m = ( y₂ - y₁ ) / ( x₂ - x₁ )
with (x₁, y₁ ) = (0, - 1) and (x₂, y₂ ) = (3, 0) ← 2 points on the line
m = = → B
the y-intercept c is where the line crosses the y- axis
that is c = - 1 ← y- intercept
