Point slope form is:

y - y_{1} = m(x - x_{1})

With y_{1} and x_{1} being the coordinate points, and m being the slope.

So the coordinate points are (4, -5), and the slope is -6 in this case.

So just substitute everything in, to get:

y - ( -5) = -6(x - 4)

Or

y + 5 = -6 (x - 4)

Answer:

Lesley purchased 1 oval bead and 4 round beands.

Step-by-step explanation:

Given that Lesley purchased 5 beads at a total cost of 80 cents, and the round beads cost 15 cents each, and the oval beads cost 20 each, to determine what are the numbers of round and oval beads Kelsey purchased, the following calculation must be performed :

5 x 0.20 + 0 x 0.15 = 1

4 x 0.20 + 1 x 0.15 = 0.95

2 x 0.20 + 3 x 0.15 = 0.85

1 x 0.20 + 4 x 0.15 = 0.80

Therefore, Lesley purchased 1 oval bead and 4 round beands.
