yes because you will need the slope and y-intercept to find the equation of a line and the point through which the line passes is the y-intercept so it is yes!!!!!!! Good Luck!!!!!!!!!!!!!

An equation of a line requires two parameters. The slope, by itself, is not enough.

The equation of line can be easily made if the slope and y-intercept are known, in the form of y equals mx plus b, where m is the slope and b is the y-intercept. The quadratic equation may need to be utilized if the previous equation cannot be used.

By finding the line of best fit and using the straight line equation formula.

Certainly you will need a graph paper of exact answer if u mean 4,3 on x-axis and 6,11 on y-axis.The formula is y=mc.It is called "Equation of straight line".

There are three variables in the equation. In order to find numbers for all of them,you need three separate independent equations.As it is now, the graph of that equation is a line in 3-dimensional space, andevery point on the line is a 'solution' to the equation. We don't have to tell youhow many points there are on a line, do we ?

If the x intercept is a and the y intercept is b, then the equation of the line is bx + ay = ab

As for example in the straight line equation of y=3x+5 the slope is 3 and the y intercept is 5
