Question

Passes through (1, -1) and (2,0)

Answer 1

Answer:

y = x - 2

Step-by-step explanation:

1. Find the slope - change in y/change in x

$\frac{0-(-1)}{2-1}$ = 1

Slope is 1

2. Find y-intercept

y = x + b

Substitute a point (2,0)

0 = 2 + b

b = -2

3. Put the equation together

y = x - 2
