Explain how to graph the equation y = 2x - 3 without using a table of values.

Y = mx + c

m is the gradient of the graph, for each time you go across 1 x you go up y 'm' times, in your case you go up twice each time you go across once along x

c is the y intercept, the number where the y axis is cut and where you should start drawing your graph

Y=m times x plus b

M = 2 (slope)

X = x (variable)

B = - 3 (y-intercept)
