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
How can you use a scatter plot to find an equation of a trend line?
By finding the line of best fit and using the straight line equation formula.
How do you find the equation oa straight line?
It depends on what information you have to start with.
Why do you need to find the equation of a line?

Is a linear equation straight?
The word straight doesn't really apply to an equation. However the graph of a linear equation is a straight line.
Does an equation allow you to find the x and y coordinates of any point on the xy plane?
Yes if it is a straight line equation
