Best ResponseYou've already chosen the best response.2Solve for y to get \[\Large 2x  4y = 10\] \[\Large 2x  4y{\color{red}{2x}} = 10{\color{red}{2x}}\] \[\Large 4y = 2x+10\] \[\Large \frac{4y}{{\color{red}{4}}} = \frac{2x+10}{{\color{red}{4}}}\] \[\Large \frac{\cancel{4}y}{\cancel{4}} = \frac{2x}{4}+\frac{10}{4}\] \[\Large y = \frac{1}{2}x  \frac{5}{2}\] The last equation is in the form y = mx+b where the slope is m = 1/2

Best ResponseYou've already chosen the best response.2Your method would work only if you had 2 points. But you had the right idea somewhat

Best ResponseYou've already chosen the best response.2Also, the two points are (5,0) and (0,2.5) notice how the 2.5 is negative

Best ResponseYou've already chosen the best response.2and the slope formula is \[\Large m = \frac{y_{2}y_{1}}{x_{2}x_{1}}\] the y difference is up top. So you had that mixed up as well
