as i spoke back b4 in ur diverse questions u purely hafta plug indoors the section to the x so the 1st one could be: y=4*(-a million)-(-a million)*2 4*-a million is -4 and -a million circumstances 2 is -2 -4 minus -2 is -2 i choose to propose didnt u learn a thank you to try this?

Solve for y:
y - 1/2 = 4[x - (-1)]
y - 1/2 = 4[x + 1]
y - 1/2 = 4x + 4
y = 4x + 4 + 1/2
y = 4x + 8/2 + 1/2
y = 4x + 9/2
y - 1/2 = 4[x - (-1)]
y - 1/2 = 4[x + 1]
y - 1/2 = 4x + 4
y = 4x + 4 + 1/2
y = 4x + 8/2 + 1/2
y = 4x + 9/2

y - 0.5 =4(x-(-1))
simplfy terms y - 0.5 =4(x+1)
a negative times a negative is equal to a positive so the - in front of the (-1) will make it equal to +1.
distribute the 4 in the term 4(x+1) by multiplying the 4 by both terms in the parentheses.
you get y - 0.5 = 4x +4.
then get y by itself by moving the - 0.5 to the other side by adding 0.5 to both sides. this will cacel the -0.5 in y - 0.5.
you get y= 4x + 4.5 (or y = 4x + 4 + 0.5)
simplfy terms y - 0.5 =4(x+1)
a negative times a negative is equal to a positive so the - in front of the (-1) will make it equal to +1.
distribute the 4 in the term 4(x+1) by multiplying the 4 by both terms in the parentheses.
you get y - 0.5 = 4x +4.
then get y by itself by moving the - 0.5 to the other side by adding 0.5 to both sides. this will cacel the -0.5 in y - 0.5.
you get y= 4x + 4.5 (or y = 4x + 4 + 0.5)

Y-1/2 = 4(X-(-1))
Y-1/2 = 4(X+1)
Y-1/2 = 4X+4
Y = 4X+4.5
OR
Y-4.5 = 4X
____ __
4 4
X = (Y-4.5)/4
THATS REAlly THE ONlY THiNG YOU CAN DO BECAUSE YOU CANt SOlVE FOR EiTHER X NOR Y.

y = 4x + 9/2

y-1/2=4x+4
add 1/2 to the other side
y=4x+4 1/2
your slope is 4 and your y intercept is 4 1/2
so you go up 4 and over 1
and you begin at 4 1/2
add 1/2 to the other side
y=4x+4 1/2
your slope is 4 and your y intercept is 4 1/2
so you go up 4 and over 1
and you begin at 4 1/2
2009-01-15 5:26 am
Y=4X+4 1/2
X=(Y- 4 1/2)/4
X=(Y- 4 1/2)/4
