Question

Choose the equation below that represents the line passing through the point (-2, -3) with a slope of -6.

Answer 1

standard linear equation is y = mx + c
gradient = -6
so eqn is y = -6x + c
now to find c
substitute the coordinates into the equation
-3 = -6( -2) + c
-3 = 12 + c
c = -15
so
y = -6x -15
