what is the slope intercept form for points 6,8 10,3 please explain
@texaschic101
First you have to find the slope m using (y2-y1)/(x2-x1), where 6 is x1, 8 is y1, 10 is x2, and 3 is y2
please i need helpp
slope = (3-8)/(10-6). what is the slope?
-5/4 @larryboxaplenty
Good, now we put in into slope intercept form, We can choose either points, I will pick (6,8). y-y1=m(x-x1) where y1 is 8, m is (-5/4), and x1 is 6
Plug it x1 and y1, and solve for y.
since -5/4 =-1.25 i out that in as m
@larryboxaplenty
y-(8)=(-5/4)(x-6) solve for y
can u walk me throught the steps of that
y-8=(-5/4)(x-6) keep y-8 alone for now, and distribute the (-5/4) to the x and -6
What do you get
for -5/4 x6 i got 7.-5 and the x just stays right
Kind of hard to read, but yes. You get (-5/4)x+7.5
Now you have y-8=(-5/4)x+7.5 You want the y by itself on the left side so solve for y
i really dont know what to do from here
You want to get rid of the negative 8 on the left side, so you add 8 on both sides of the equation.
visual please. i am a visual learner
y-8+8=(-5/4)x+7.5+8 -8+8=0, so: y=(-5/4)x+7.5+8 y=(-5/4)x+15.5 that is the equation.
do you understand?
yes now i do thanks you
Remember, if you have 2 points: 1)find slope 2)use a point in slope-intercept form 3)solve for y
