What is the equation of the straight line that passes through two points (x_1, y_1) and (x_2, y_2)?

(y - y_1) / (x - x_1) = (y_2 - y_1) / (x_2 - x_1) (correct)

y = mx + c

y - y_1 = m(x - x_1)

x = mx + c

What is the gradient of the line when the gradient-point form is y - y_1 = m(x - x_1)?

m = y_1 - y_2

m = x_1 - x_2

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

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

What is the value of c in the gradient-intercept form y = mx + c?

c = y_1 + mx_1

c = x_1 - y_1

c = y_2 - mx_2

c = y_1 - mx_1 (correct)
