Best ResponseYou've already chosen the best response.0Finding the yintercept first usually works better. To find the yintercept, let x = 0 and find the resulting yvalue. This is also zero. This means that the yintercept occurs where x = 0 and y = 0 (at the point (0,0)). Then plot more points by putting more x's in. Let x = 2 to get y = 1 (2, 1) is the point. Let x = 4 to get y = 2 (4, 2). Then connect the dots to form the straight line.

Best ResponseYou've already chosen the best response.0i'm a little confused, so the y intercept is 0? i understand plotting the points, thanks!

Best ResponseYou've already chosen the best response.0ok i think i understand. so what happens in the equation y=2/3x+5? is the y intercept 5? and how do i graph that equation?

Best ResponseYou've already chosen the best response.0The yintercept is 5. If you let x = 0, then you would just get y = 5 as your yintercept. Graph the equation by picking more xvalues, getting yvalues, and connecting the dots.

Best ResponseYou've already chosen the best response.0ok, i'm getting the hang of it. so for 5x15=3y when i plug in the zeros, my first point would be (3,0) and the second would be (0,5) then i connect them with a line.

Best ResponseYou've already chosen the best response.0for y=2x+3, would my slope be 2 since the formula is y=mx+b?

Best ResponseYou've already chosen the best response.0so for the equation x=5y=10, is the slope 1/5?

Best ResponseYou've already chosen the best response.0x  5y = 10... the slope is going to be a positive 1/5. You subtract x on both sides to get 5y = x + 10. Dividing by 5 gives you y = 1/5x  2.

Best ResponseYou've already chosen the best response.0Oh, whoops. You were right. Confused on the equals sign typo. If x + 5y = 10... then 5y = x + 10, and y = 1/5x + 2

Best ResponseYou've already chosen the best response.0so going back to the equation y=2/3x+5, i'm a little confused doing my math to get points to plot on the graph ... i keep getting fractions when i multiply and it makes it hard to plot a point.

Best ResponseYou've already chosen the best response.0If you pick multiples of 3 (like 3, 6, 9, etc.), it'll cancel out the 3 on the bottom. 3 * 2/3 for example, gives 2. 6 * 2 / 3 = 2. Now you have a 2/3, so you'll get different results when you multiply it by 3, 6, 9, etc.

Best ResponseYou've already chosen the best response.0Whoops, 6 * 2 / 3 = 4
