How do you find the slope and intercept to graph #y=2x#?
Standard for of equation is
where m is the gradient (slope) and c is the y-intercept. The gradient is the amount of up for the amount of along. So a gradient of say
In your case the m is of value 2. This may be quite correctly written as
The line will cross the y-axis at
So your graph crosses the y-axis at
