I don’t know how to find y number 9:)

1 answer:

5 0

Awe, okay, I learned how to do this. Direct variation equation y=kx. So, I believe you're asking for help on 9 so here, y=k/X=k=y/x =-5/2. Now, plug back the fraction into y=kx like this, - 5/2(8) since X is 8 in this case, which equals - 20. What was just solved was your y for when X is 8.

Complete the point-slope equation of the line through (6,4)and (7,2)

kotykmax [81]

The slope is the change in y over the change in x, so it's (4-2)/(6-7)=2/-1=-2. Point slope form is y<span> – </span>y1<span> = </span>m(x<span> – </span>x1<span>), so we can plug in a point (6,4) to get
y-6=-2(x-4)</span>
