Answer:

Step-by-step explanation:

Yes y varies directly with x.

From the equation of a straight line,

y = mx+c, calculating the gradient (m) after doing the plotting with the given coordinates, (m) =4/5.

Therefore the equation of the line is

y= 4/5x + c and c is the point at which the line intersected the y - axis which is roughly 15.

Therefore the equation of the line id

5y = 4x + 75.
