You can put this solution on YOUR website! Graph 2x-y=4 The easiest method is to think about where this line will cross the x-axis and the y-axis.

-(y = -2x + 4) ==> 0 = 6x - 6 3. Find the value of the non-canceled out variable. 0 = 6x - 6 +6 +6 6 = 6x 1 = x 4. Plug this value for x into one of the equations (it does not matter which one) and solve for y. y = 4x - 2 y = 4(1) - 2 y = 4 - 2 y = 2 5. You now have your x and y values. Simply plug them into coordinate form (x,y) for your ...

To find the distance from this point (0,4) to the line y = 2x - 4, use the general formula for the distance from the point (p,q) on the coordinate plane to the line Ax + BY + C = 0 d = . In your case the point is (0,4) and the line is 2x - y - 4 = 0, so A= 2, B= -1, C= -4, p= 0 and q= 4, and the formula (1) takes the form d = = = = = 3.577 ...

You can put this solution on YOUR website! Find the slope of the graph Step 1. To find the slope of this equation in standard form you need to change it to slope intercept form given as y=mx+b where m is the slope and the y-intercept is b when x=0 and at point (0,b).

2x-4 = y or y = 2x-4 Comparing this with the general form of the slope-intercept equation: y = mx+b, you can see that the slope, m, = 2. So now for your new equation, you can write: y = 2x+b But you still need to find the value of b, the y-intercept of the new equation. You can use the coordinates of the given point (2, -3) to do this.

You can put this solution on YOUR website! y = |2x-4| when 2x-4 is positive or zero then y = 2x-4 when 2x-4 is negative then y = -(2x-4) That is, when 2x-4 ≧ 0 then y = 2x-4 when 2x-4 0 then y = -(2x-4) Solve 2x-4 ≧ 0 2x ≧ 4 x ≧ 2 Solve 2x-4 0 2x 4 x 2 Therefore when x ≧ 2, then y = 2x-4 when x 2, then y = -(2x-4) Normally that is written: And you might want to write -(2x-4) as -2x+4 ...

y = 2x - 4 y = 4x - 10 Since both expressions are equal to y, then they are equal to each other. 2x - 4 ...

The original line is y = -2x + 4 with m=slope=-2 and y-intercept 4. Parallel lines have the same slope, so the new line's slope is -4 and it's general equation is y = -4x + b. The new line passes through (-4,3), so find b by plugging those values (x,y) in for x and y.
