Find the equation of a line given the gradient and a point

Straight line graphs

Algebra

Find the equation of a line when the gradient and any point (not the y-intercept) is given without reference to the graph. Substitute the point into the formula y=mx+c to find c OR find the equation of a line when two points are given, one being the y-intercept without reference to the graph by using the formula y=mx+c and finding the gradient from the 2 points
