The third one, this is because you take your y2 and y1 values (y2=0 and y1=9 because these are the two y values given to you from each coordinate) and subtract 0-9. then you do the same, but with the x2 and x1 values. so your x1 value is 3 and your x2 value is 0, so you subtract 0 from 3. divide your second answer from the first answer, to get a gradient of -1/3 x. now using the first coordinate (0,9) you know that the y coordinate is 9. as the x value =0, we know that the line is passing through the y axis at 9 so 9 is your y intercept. this gives you the equation -1/3x+9. hope this helped and wasn't too confusing!
The solution is the set of numbers that can be written in place of
all the variables and make all of the equations true.
If you're asking for the actual numbers, there's nobody in the world
who could find those without seeing the system of equations.
No. A solution is any co ordinated that lies in the blank space on the graph. (-2,-3) is in the blue shades section so it is not a solution.
