i need this done tonight or ill fail the class :((((
what is hardest part for you?
all of it , i dont get anything about slope it confuses me and im nervous i wont get it done tonight
mm.. okay. let's do first part
now we don't know what the red line is . So let's assume that y= ax + c now this is our red line
now look at red line on your graph. it intersects y axis and x axis at -0.5 and 0.5
it looks like it lands on 4?
it looks like 0.5, 4 where the line meets
well it should be -1. not -0.5
i said wrong before
oh okay i get now ! whats the next step
okay now have two points. (0,-1) and (0.5,0) you can plug each point in our red line equation and find "a" and "c"
can you give me values for a and c
let me do that
y = ax + c take our first point (0,-1) now put the values -1 = a*0 + c
c = -1
um ookay ??
okay do the same for next point (0.5,0)
and give the answer for "a" :)
since we know c = -1, we don't need to carry c. y= ax - 1 0 = a*0.5 -1 a*0.5 = 1 a = 2
so far is -1=2*0.5-1
"-1" = 2*0.5 -1 here "-1" is wrong. y value of (0.5,0) is 0. not -1
so then what is Y
y = 0
okay how do we solve
and you get a = 2
"so 0=2*0.5-1" here you still don't know what the a is. so don't add 2 there. correct one is 0 = a*0.5 -1
now we know a = 2 and c = -1
red line is y = ax +c so put answers to the equation y = 2x - 1
this is the answer for 1st one
