Question

Work out the equation of the line which has a gradient of 2 and

passes through the point (2, 5)

Answer 1

y=2x+1

Explanation:

You use the equation y=mx+b and substitute m for the slope/gradient. Then you use (2,5) to subtitue for y and x. Solve the equation for b. Then you have your slope and b, and you can make your equation from this.
