Answer to Question #250130 in Analytic Geometry for shantel

Question

Describe verbally how to solve y mx c = + . What assumptions have you made about the value of m ? 

Answer 1

One form of the equation of a straight line is called the slope-intercept form because it contains information about these two properties.

The equation of a straight line:

Any equation of the form $y = mx + c$ where m and c are fixed numbers, (i.e. constants), has a graph which is a straight line.

For example, $y = 3x + 5, y = \frac{2}{3} x + 8$ and $y = −3x − 7$ all have graphs which are straight lines.
