Question

What does a+c in a pair of straight linesequation give?

Answer 1

here the answer is

a+c=180

Answer 2

Answer:

If the given equation is in the form ax2 + 2hxy + by2 = 0, by factoring we may get two linear factors and that will be the separate equations for the straight line.

If the given equation is in the form ax2 + 2hxy + by2 + 2gx + 2fy + c = 0, then we have to take the first three terms and find factors.

The general equation of a straight line is y = mx + c, where m is the gradient, and y = c is the value where the line cuts the y-axis. This number c is called the intercept on the y-axis.
