To begin with, let's establish that the formula of this line is in slope-intercept form as follows:
y = mx
The formula for this line isn't:
y = mx + b
This is as this line doesn't have a y-intercept ( b ) as it passes through the origin instead. This means that ( b ) would be rendered useless in this formula as it would just bring us back to the y = mx formula as displayed below:
y = mx + b y = mx + 0 y = mx
Moving on, for ( m ), we need to find the gradient of the line as displayed below:
m = gradient m = rise / run m = 10 / 2 m = 5
Now, we must simply substitue ( m ) into the formula in order to obtain the equation for this line as displayed below:
