-8x + 4y = 28 Add 8x to each side: 4y = 8x + 28 Divide both sides by 4: y = 2x + 7
8x - y = 31 <=> y = 8x - 31. 5x + 3y = 23 => 5x + 3 * (8x - 31) = 23 <=> 5x + 24x - 93 = 23 <=> 29x = 23 + 93 <=> 29x = 116 <=> 29x/29 = 116/29 <=> x = 4. y = 8x - 31 => y = 8 * 4 - 31 <=> y = 32 - 31 <=> y = 1.
Without any equality signs the given expression is not an equation and so therefore any solutions are not possible.
x=1, y=1
To convert the equation 8x - 5y = -40 into slope-intercept form (y = mx + b), where m is the slope and b is the y-intercept, you need to solve for y. First, isolate y by subtracting 8x from both sides to get -5y = -8x - 40. Then, divide by -5 to get y = 8/5x + 8, which is the slope-intercept form of the equation. The slope is 8/5 and the y-intercept is 8.
4x + 3y = 8x + y so 3y - y = 8x - 4x ie 2y = 4x so y = 2x
-8x + 4y = 28 Add 8x to each side: 4y = 8x + 28 Divide both sides by 4: y = 2x + 7
(y - 2)(2y + 5)
If you mean slope 8 and y intercept 3 then the equation is y = 8x+3
8x - y = 31 <=> y = 8x - 31. 5x + 3y = 23 => 5x + 3 * (8x - 31) = 23 <=> 5x + 24x - 93 = 23 <=> 29x = 23 + 93 <=> 29x = 116 <=> 29x/29 = 116/29 <=> x = 4. y = 8x - 31 => y = 8 * 4 - 31 <=> y = 32 - 31 <=> y = 1.
Without any equality signs the given expression is not an equation and so therefore any solutions are not possible.
x=1, y=1
It is a straight line equation that needs to be rearranged into slope-intercept form as follows:- 8x+20y = -80 20y = -8x-80 y = -0.4x-4
If you mean: 5x -2y = 10 then y = 2.5x -5 whereas -5 is the y intercept and 2.5 is the slope
Y-8x plus 9y equals 10y-8x.
8x-7y=42 24x+y=170 An easy way to begin is to solve for one variable in one of your two equations. I will use the second equation to solve for y: 24x+y=170 y=170-24x This solution for y will then be plugged into the first equation so the equation will be of one variable, and therefore solvable: 8x-7y=42 8x-7(170-24x)=42 8x-1190+168x=42 176x=1232 x=1232/176=7 x=7 The solution we made for y can now be used with the solved value of x to find y's numerical value. y=170-24x y=170-24(7) y=170-168 y=2 So, finally, we get that x=7 and y=2
the slope is 6 and the y intercept is 8x
