find the slope and y-intercept 2x-y=5 n graph line
if you arrange it like y=2x-5 than you can read off the slope. It is the multiplier of x, so it is 2. For the y-intercept, you have to set y=0 and than 2x-0=5 so x=5/2
-2/-1 = slope = 2 yint = x=0; -5
oh yeah my was the x intercept
:)
the slope is; ax+by = c -a/b
equation of a line is equation of a line :)
so how do i wite the equation
y = (-a/b)x +c slope = -a/b
depends on which form of the equation you want to write
ax +by - c = 0 ax + by = c y = -(a/b)x + c y-y1 = (-a/b)(x-x1)
x = x1 + at y = y1 + bt z = 0
how did you find the y intercept
what is the definition of a y intercept?
what value is y when the graph is caught by the y axis ? the y axis is the x=0 axis what is the value of the equation when x=0?
2(0) - y = 5 -y = 5 y = -5
(0,-5)
oh ok so what was the -2/-1 for
