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

To determine which points are on the line given by the equation ( y = 2x ), you can substitute the x-coordinate of each point into the equation and see if the resulting y-coordinate matches the point's y-coordinate. For example, if you have the point (1, 2), substituting ( x = 1 ) gives ( y = 2(1) = 2 ), so this point is on the line. Repeat this process for each point to find which ones satisfy the equation.
If the slope is 2/3 and the coordinate is (2, -1) then the straight line equation is 3y=2x-7
The y coordinate is given below:
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
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
