Question 237384
The equation for a line is : {{{Y = m*X + B}}}
Where m is the slope of teh line and B is the Y-intercept

You were given (0,-2) which means that when X=0, then Y = -2.
You were also given the slope of the line, 6.6.

All you need to do now is substitute the values in for the variables

{{{Y = m*X + B}}}
{{{-2 = 6.6*(0) + B}}} Since 6.6 * 0 = 0, you are left with B = -2

So the equation for your line is; {{{highlight(Y = 6.6*X -2)}}}
