220 = 2(50) + b 220 = 100 + b b + 100 = 220 b = 120. Now I know the b and the m, so I can finally write the full y=mx + b form of the equation: y = 2x + 120. For the other questions, I can look at the equation I got. The y-intercept (b value) is $120. That means that we are adding $120 on to the price all the time. That's the price for the ... Aug 14, 2015 · Example 1. A man travels at 3 mph in still water. If the current’s velocity is 1 mph, it takes 3 hours to row to a place and come back. How far is the place? Solution.

More than one equation to be solved at the same time is know as this., The ratio of rise to run, The answer to an equation or system of equations., y = mx + b is more formally known as this. The first thing you should recognize is the key word for slope, per. Since John can mow 2 lawns per hour, we know that this is the slope (m). Also, since the problem states per hour, we know that the variable associated with the slope is h. At this point, I realize that the only problem that has, 2h is letter b.
