Question

A straight line with the equation y=ax-3 goes through the point (2,11). Work out the value of a

Answer 1

The value a is 7.

What is Straight Line?

A line is simply an object in geometry that is characterized under zero width object that extends on both sides. A straight line is just a line with no curves.

Here, the given equation of line

      y = ax -3

line passing through point (2, 11), then

    11 = a X 2 - 3

    11 + 3 = 2a

     2a = 14

      a = 7

Thus, the value a is 7.
