(0,6)
Explanation:
The line passing through (9,5) and (2,8) has a gradient of
The difference in the y values of the two points divided by the difference in the x values.
The general equation of a line is
where m is the gradient and c is the y intercept
So the equation of the line passing through (7,3) with a gradient of
But we know the point (7,3) is on the line so substitute in the values to get the equation as
When x =0 y=6
