4x+8y=16
Move the 4x to the other side to put it into slope intercept form.
8y=-4x+16
Then divide by 8.
Y=-1/2x+2
The slope is -1/2 and the Y intercept is 2.
Look at the denominators. The second fraction's denominator is 3 times the first fraction's denominator. Since the fractions are equal, it means you have to multiply the first fraction's numerator by 3 too. So, b=9. Good luck!
