03.03 Linear Functions
1. The equation we have is 2x+3y=1200. The first thing you would need to do in the equation is subtract 2x to both sides. 2x cancels out and now we subtract 2x and 1200. You would end up getting 3y=2x-1200. Then finally, you would have to divide everything by -3. Your final answer for this question is y=-2/3x+400. Your slope is -2/3 and your y-intercept is 400.
2. So we know that our slope is -2/3 and the y-intercept is 400. You have one point on the straight line at (0, 400).Since the slope is negative, x is going to increase and y is going to decrease. And since the slope is a fraction, there will be rise over run. For the slope, you have to take 3 steps on the x-axis and the y is going to go down
