in order to solve this problem you have to solve for x first wich you are given the data to pre forme so x=4 and x.2=8 and 8=y and y-4=4=a=x so a+8=12 and 12=b
y is the value on the y axis on Cartesian x-y graph where x is the horizontal axis and y is the vertical axis. Fora given value of m (slope) and b ( y intercept) you vcan calcualte y for any value of...
