Use the following equation:
y = mx + c
where m = the gradient and c = the point at which the line intercepts the Y axis. M is calculated by Change in Y / Change in X... For example;
The line moves 3 'slots of y' and 5' slot of x' thus M = 3/5 = 0.6
thus y = 0.6*x + c
So if you want to know what y is when x is 5 for example, put five in the place of 'x', and put the point of intercept in as C.

Why do you need to find the equation of a line?
So that you can plot out the points of a straight line on graph paper.
When an equation forms a straight line what is it?
a linear equation.
Find the slope of the line whose equation is 4x - 6y 8?
Without an equality sign the given terms can't be considered to be a straight line equation.
Is an equation whose grap is a straight line?
A linear equation.
What is the slope of a line that is parallel to the line represented by the equation y-5x5?
Without an equality sign it is not an equation but when a straight line equation is parallel to another straight line the slope remains the same but the y intercept is different
