The y-intercept of that line is the point (0, 21).
All points whose y-coordinate is twice its x-coordinate.

The y coordinate is given below:
If the slope is 2/3 and the coordinate is (2, -1) then the straight line equation is 3y=2x-7
We will be able to identify the answer if we have the equation. We can only check on the coordinates from the given vertex.
By solving the simultaneous equations the values of x and y should be equal to the given coordinate
Without the inclusion of an equality sign and not knowing the plus or minus values of the given terms it can't be considered to be a straight line equation
