Standard form is Ax +By =c
y = -4/5 x -7
multiply by 5
5y = -4x -35
add 4x to each side
4x +5y = -35
multiply by -1
-4x -5y = 35
Choice D
Use exponential law, we have
For 2 red beads, Yasir uses 5 yellow beads,
2+5=7 is less that the total number of beads per bracelet.
so we multiply both (2 and 5) by 2, and get (4 and 10) red beads and yellow beads.
4+10=14, so the total number is between 9 and 15 as required.
Answer:
4 red beads
10 yellow beads
The standard form for an equation is y=mx+b. You find the slope by using the formula of rise over run. This means that for problem 6 you first look to see if its positive or negative slope. The slope is positive if the line is going uphill and if its going downhill its negative. The slope would be negative for number 6 because it is going downhill. Then for the actualy slope you would start with rise. So you look at the point (0,1) and go up 3 until you hit the line of the other point and run over 2. So your slope would be -3/2.

(1, -3)
