Transfer the equation into the standard format y = mx + c, where 'm' is the slope 7x - 3y = 4 : 7x - 4 = 3y 3y = 7x - 4 y = 7/3x - 4/3 : The slope is 7/3.
7x+3y=-52 3(8x-y=-74) 7x+3y=-52 24x-3y=-222 7x=-52 + 24x=-222 31x=-274 x=8.8387
y=mx+b 7x+3y=21 3y=21-7x *****_ y=7-2.3x *****_ m= -2.3 negative
What is the slope-intercept form of 7x-3y equals 4
4xy+1=3y-7x 4xy-3y=-7x-1 y(4x-3)=-7x-1 y=(-7x-1)/(4x-3)
It's just a mathematical polynomial: 7x + 3y.
Transfer the equation into the standard format y = mx + c, where 'm' is the slope 7x - 3y = 4 : 7x - 4 = 3y 3y = 7x - 4 y = 7/3x - 4/3 : The slope is 7/3.
7x+3y=-52 3(8x-y=-74) 7x+3y=-52 24x-3y=-222 7x=-52 + 24x=-222 31x=-274 x=8.8387
If the equation is 7x - 3y = 21 then (3, 0) and (0, -7).
y=mx+b 7x+3y=21 3y=21-7x *****_ y=7-2.3x *****_ m= -2.3 negative
What is the slope-intercept form of 7x-3y equals 4
4xy+1=3y-7x 4xy-3y=-7x-1 y(4x-3)=-7x-1 y=(-7x-1)/(4x-3)
9x-3y=63 7x-3y=45 -3y=63-9x -y=21-3x y=-21+3x 7x-3(-21+3x)=45 7x+63+9x=45 7x+9x=45-63 16x=-18 x=-1.125 y=-21+3(-1.125) y=-24.375 (-1.125,-24.375)
(14x-2y)+(7x-3y)+(-3x) = 14x-2y+7x-3y-3x =(14+7-3)x-(2+3)y =18x-5y
(7x-3y) + (2x+5y) = 9x+2y
x+7x+3y-y =8x+2y =2(4x+y)
7x-3y=21 Think of it this way. Block 3y or multiply 3(0)=0. Then you get: 7x=21 X=3 In vice versa, block 7x or multiply 7(0)=0 and look at: 3y=21 Y=7 So an ordered pair is (x,y) Thus, you get (3,7)
