but its pretty simple

not for me i really suck at math, please help me step by step

is this correct f(x) = -(1/2)x + 2 f(x) = (9/2)x - 8
anonymous
  • anonymous
not sure how to make the fraction symbols for -1/8 and 9/2
dumbcow
  • dumbcow
thats ok me neither. both of these are linear of the form y = mx+b m = slope (rise/run) b = y-intercept (where it crosses y-axis) Now we need to graph each one First identify y-intercept for our first point 1) b = 2 2) b = -8 put these points on the graph on the y-axis
dumbcow
  • dumbcow
Next we look at slope to find second point 1) m = -1/2 This means starting at our y-intercept we go down 1 and over to right 2, repeat process for additional points 2) m=9/2 This means starting at y-intercept go up 9 and over to right 2 connect points to make each line point where they intersect is the solution
anonymous
  • anonymous
in the begining the first points b=2 b=-8 is that graphed as (2,-8)?
dumbcow
  • dumbcow
oh sorry i meant 1) to mean line 1 and 2) to mean line 2 they are separate points the x value is always zero for the y-intercept (0,2) (0,-8)
anonymous
  • anonymous
ok im really bad at this stuff
dumbcow
  • dumbcow
when you think y-intercept, think y-axis....points will be directly on y-axis
anonymous
  • anonymous
ok, so back to m=-1/2 and m=9/2
dumbcow
  • dumbcow
yes start with the first one go to starting point (0,2) -1 means go down 1 2 means go right 2 plot a point
anonymous
  • anonymous
ok so after i graphed them i came up with (2,1)?
dumbcow
  • dumbcow
correct this is the point where they cross
anonymous
  • anonymous
ok do u have time to help me with more
dumbcow
  • dumbcow
for a little bit, if nothing else i'll give you the steps
anonymous
  • anonymous
ok f(x)=-1/8x-3 g(x)=5/8x-9
dumbcow
  • dumbcow
same thing solve by graphing
dumbcow
  • dumbcow
do the exact same steps we did before the only thing that changes is the slope and y-intercept
dumbcow
  • dumbcow
for f(x) = mx + b m=-1/8 b=-3
dumbcow
  • dumbcow
can you graph the first point from there
anonymous
  • anonymous
start at 0 and go down the y to -3
dumbcow
  • dumbcow
good
anonymous
  • anonymous
same for (0,-8)
anonymous
  • anonymous
they intercept at (2,-3) is that correct?
dumbcow
  • dumbcow
careful the -8 was part of the slope for the first line
dumbcow
  • dumbcow
the other y-intercept would be (0,-9)
anonymous
  • anonymous
right , after i graphed them i got (2,-3)
dumbcow
  • dumbcow
remember what the difference between m and b are another way to think of it is the slope is always the number associated with the x, y-intercept is always the constant value
dumbcow
  • dumbcow
no you should get (8,-4)
dumbcow
  • dumbcow
starting at (0,-3) go down 1 over right 8
anonymous
  • anonymous
ok i got it
dumbcow
  • dumbcow
ok good keep repeating those steps gotta go good luck
anonymous
  • anonymous
thank you so much
dumbcow
  • dumbcow
your welcome
anonymous
  • anonymous
thank you so much
