I have a slope of -3/4 and the y-intercept at 8
the equation looks like:
y= -3/4x + 8
can someone tell me if i'm correct when i'm graphing it.
the two points that cross in the x axis and y are
(0,8) and (10.5,0) am i correct?
correct on the formula. correct on the intercepts.
what about if i have this one:
y = -2x + 4
then would my graph coordinates where it crosses be:
(0,4) and (2,0)
and then this one:
equation: y = 5x -2
then it will be: (-2,0) and i don't know what will the other be?
right on the first.
On the second
y = 5x -2
if x=0, then y=-2 so (0,-2)
and if y=0, then
0=5x-2 or x=2/5 so (2/5 , 0)
so then it would be(0,-2) and it will actally be (.4,0)
yes, although the word "actually' implies that 2/5 is not correct but it is. 2/5 if you wish to use fractions and 0.4 if you wish to use decimal equivalents.
okay thank you for helping me relieve my unsureness.

im learning this!! does anyone know the answeer to y=6/5x-2 (do a t-chart) i don't know wat to do!
