Suppose the equation of the line is y = mx + c where m and c need to be determined.
The slope of the line = (difference in y-coordinates of the two given points)/(difference in x-coordinates of the two given points)
= (-6 - 2)/(0 - 4) = -8/-4 = 2
So m = 2 ie the equation of the line becomes: y = 2x + c where c still needs to be determined.
The point (0, -6) is on the line. That is, when x = 0, y = -6.
Substituting in the equation, -6 = 2*0 + c so that c = -6
and the equation of the line is y = 2x - 6

How do you find slope if the points aren't given?
the slope is the 'm' in y=mx+b so even if the points aren't given, if there is an equation, then you can find the slope. for example, if you have an equation like this: y=2x+5 the slope is 2 and the y-intercept is 5.

Is it easier to solve an equation for y first before finding points?
It is always easier to use an equation to find points since all you would have to do is substitute values into the equation to find the final unknown value that will tell the point. To get the equation, however, you would usually need to have some points at the start to help derive the equation in the end.
