Best ResponseYou've already chosen the best response.0is this correct f(x) = (1/2)x + 2 f(x) = (9/2)x  8

Best ResponseYou've already chosen the best response.0not sure how to make the fraction symbols for 1/8 and 9/2

Best ResponseYou've already chosen the best response.0thats ok me neither. both of these are linear of the form y = mx+b m = slope (rise/run) b = yintercept (where it crosses yaxis) Now we need to graph each one First identify yintercept for our first point 1) b = 2 2) b = 8 put these points on the graph on the yaxis

Best ResponseYou've already chosen the best response.0Next we look at slope to find second point 1) m = 1/2 This means starting at our yintercept we go down 1 and over to right 2, repeat process for additional points 2) m=9/2 This means starting at yintercept go up 9 and over to right 2 connect points to make each line point where they intersect is the solution

Best ResponseYou've already chosen the best response.0in the begining the first points b=2 b=8 is that graphed as (2,8)?

Best ResponseYou've already chosen the best response.0oh 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 yintercept (0,2) (0,8)

Best ResponseYou've already chosen the best response.0ok im really bad at this stuff

Best ResponseYou've already chosen the best response.0when you think yintercept, think yaxis....points will be directly on yaxis

Best ResponseYou've already chosen the best response.0ok, so back to m=1/2 and m=9/2

dumbcow

Best ResponseYou've already chosen the best response.0yes start with the first one go to starting point (0,2) 1 means go down 1 2 means go right 2 plot a point

Best ResponseYou've already chosen the best response.0ok so after i graphed them i came up with (2,1)?

Best ResponseYou've already chosen the best response.0correct this is the point where they cross

Best ResponseYou've already chosen the best response.0same thing solve by graphing

dumbcow

Best ResponseYou've already chosen the best response.0do the exact same steps we did before the only thing that changes is the slope and yintercept

dumbcow

Best ResponseYou've already chosen the best response.0for f(x) = mx + b m=1/8 b=3

dumbcow

Best ResponseYou've already chosen the best response.0can you graph the first point from there

Best ResponseYou've already chosen the best response.0start at 0 and go down the y to 3

Best ResponseYou've already chosen the best response.0they intercept at (2,3) is that correct?

dumbcow

Best ResponseYou've already chosen the best response.0careful the 8 was part of the slope for the first line

dumbcow

Best ResponseYou've already chosen the best response.0the other yintercept would be (0,9)

tinaann

Best ResponseYou've already chosen the best response.0right , after i graphed them i got (2,3)

dumbcow

Best ResponseYou've already chosen the best response.0remember 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, yintercept is always the constant value

dumbcow

Best ResponseYou've already chosen the best response.0no you should get (8,4)

dumbcow

Best ResponseYou've already chosen the best response.0starting at (0,3) go down 1 over right 8

Best ResponseYou've already chosen the best response.0ok good keep repeating those steps gotta go good luck
