What is the graph of -4x plus 7y equals -28?
-4x=7y-28 -4x+28=7y -4x/7+4=y A line with a y-int of 4 and a slope of -4/7
How do you solve for y in 14x equals 7y plus 28?
14x = 7y+28 -7y = -14x+28 Divide all terms by -7 to find the value of y: y = 2x-4 which is now in slope intercept form
What is the slope of 4x-7y-28 equals 0?
If: 4x-7y-28 = 0 then y = 4/7x-4 whereas 4/7 is the slope and -4 is the y intercept
What is 3x plus 7y if x equals 6 y equals 4?
3x + 7y = 3*x + 7*y = 3*6 + 7*4 = 18 + 28 = 46
6x plus 7y equals 96 6x - 7y equals 12?
(9,6)
65x - 7y equals 371 -11x plus 7y equals 7?
(7,12)
What is 39-7y equals 18 equal?
39 - 7y = 18,-7y = 18 - 39-7y = -21-7y/-7 = -21/-7y = 3
What is the slope of the line 14y-2x equals 28?
14y - 2x = 28 ie 7y - x = 14 ie 7y = x + 14 or y = (1/7)x + 14 The slope is the coefficient of x, or 1/7
What is the slope of 14x plus 7y equals -9?
14x+7y=-9
What is the solution to 10x-7y equals -1 and -2x-7y equals -25?
10x-7y=-110x+1=7y-2x -10x-1=-25-12x-1=-25-12x=-24x=-24/-12x=210(2)-7y=-120-7y=-121=7y21/7=yy=3
Use elimination to solve the system x plus 7y equals 16 and 3x - 7y equals 4?
x+7y=16 ---------------------------1 3x- 7y=4 ---------------------------2 ------------------------------------------------------------------------------------------------------------------ 1+2 x+7y=16 3x-7y=4 4x=20 x=5 substitute x = 5 in x+7y=16 (5)+7y=16 7y=11 y=11/7
7y-2 equals 14yplus 61?
y=-9 7y-2=14y+61 7y-2-7y=14y+61-7y -2=7y+61 -2-61=7y+61-61 -63=7y -63/7=7y/7 -9=y
