7x + 10y = 4.5 : 10y = -7x + 4.5 : y = -x.7/10 + 0.45, the gradient of this line is -7/10
Two straight lines are perpendicular if the product of their gradients is -1.
Let the equation for the perpendicular line be y = mx + c
Then m x -7/10 = -1 : m = 10/7
The equation for the perpendicular line is y = x.10/7 + c
If the values of x and y for the point of intersection are provided then these can be substituted in the perpendicular line equation and the value of c obtained.
If appropriate, the equation can then be restructured to a format similar to the original equation.
