Question

Which equation represents the line passing through points A and C on the graph below?

On a coordinate plane, point A is at (2, 3), point B is at (negative 2, 1), point C is at (negative 4, negative 3), and point D is at (4, negative 5).
y= negative x minus 1
y = negative x + 1
y = x minus 1
y = x + 1

Answer 1

Find the slope: (3 − (−3)) / (2 − (−4)) = 6/6 = 1.
So the line is y = x + b. Plug in (2,3): 3 = 2 + b → b = 1.
Equation: y = x + 1.
