But you cannot do the same by a variable like X, y etc.. the reason is we do not know the value of variable and it could be 0, but by dividing by a variable, we negate that possiblity..

You can put this solution on YOUR website! We can put this into the slope-intercept form to get the slope and y-intercept to determine two ordered pairs. First we need to convert the equation …

You can put this solution on YOUR website! Looking at we can see that the equation is in slope-intercept form where the slope is and the y-intercept is note: really looks like Since this tells us …

Question 213417 This question is from textbook algebra 2 : how do i graph y=2x+7 This question is from textbook algebra 2 Answer by Theo (13342) (Show Source):

You can put this solution on YOUR website! y=2x y=-x+6 Let's solve this system using substitution. Substitute 2x instead of y into the second equation, because we know that y = 2x. …

Question 151069: graph: y = 2x +8 Answer by vleith (2983) (Show Source):

The y-intercept is at -1 and it has a slope of 2. Therefore, you mark a point at the point (0,1) and then go up 2 and right 1. Put another point here. go up 2 and right 1. Put another point here. …

You can put this solution on YOUR website! Hi, In answer to Your reply: the standard slope-intercept form y = mx + b (found by simply by expressing the linear equation in terms of y) is a …

Also, the y-value for (which is two units from the axis of symmetry) is equal to the y-value of (which is also two units from the axis of symmetry). So when , which gives us the point (2,-9).

­If y - 2x ≤ 2 and 2y + 2x ≤ 12, what is the maximum possible value of y? A) 4/3 B) 2 C) 4 D) 14/3 E) 6­
