  • Equation of a Straight Line - Math is Fun

    With that equation you can now ..... choose any value for x and find the matching value for y. For example, when x is 1: y = 2×1 + 1 = 3. Check for yourself that x=1 and y=3 is actually on the line. Or we could choose another value for x, such as 7: y = 2×7 + 1 = 15. And so when x=7 you will have y=15
