x=7 and y=4
Solving by the elimination method: x = 7 and y = 2
-8x + 4y = 28 Add 8x to each side: 4y = 8x + 28 Divide both sides by 4: y = 2x + 7
Slope is amount of change in y each time you change the x value one. In this case y=8x+7 the slope is 8 and the y intercept is when x is 0. In the case the y intercept is 7.
There is not a way to give the answer to this equation. You will have to give me the value of the letters.
If: y = 8x+7 then the y intercept is 7 and the slope is 8
the slope is 6 and the y intercept is 8x
7 is the y intercept
x=7 and y=4
Y-8x plus 9y equals 10y-8x.
Use the Formula Y=mx + b -48x + y = 7 -8x + 6y = 7 ~Subtract -48x ~Subtract -8x You now get y= 48x + 7 You now get 6y= 8x + 7 ~ Divide 6 by each # on the opposite side. The slope (m) is 48/1 You now get y= 4/3x + 7 The slope (m) is 4/3 In order to be perpendicular you need to have a negative (opposite reciprocal slope). 48/1 and 4/3 are NOT negative reciprocals and thus are NOT perpendicular.
Solving by the elimination method: x = 7 and y = 2
-8x + 4y = 28 Add 8x to each side: 4y = 8x + 28 Divide both sides by 4: y = 2x + 7
If you meant, your two equations are y=2x+2 and y= 8x+1 your vertex will be at x=1/6 and y=7/3 you can plug these in and they will check out. but if you meant, y=(2x2) +8x+1 y=4+8x+1 y=8x+5 and then you only have one line so there will be no vertex. but the y intercept is at (0, 5) and your x-intercept at (-5/8, 0) if neither are these are what you are saying, sorry, and maybe try and repost and I will help you out.
Slope is amount of change in y each time you change the x value one. In this case y=8x+7 the slope is 8 and the y intercept is when x is 0. In the case the y intercept is 7.
4x + 3y = 8x + y so 3y - y = 8x - 4x ie 2y = 4x so y = 2x
