Answer:

y = m x + b equation of a straight line

m m' = -1    condition for perpendicular lines

If y = 4 x - 7     then m = 4 so m' = -.25

Y = -.25 X + A      we need to find A

A = Y + .25 * 8 = 2 + 2 = 4

Y = -.25 X + 4

Check:

2 = -.25 * 8 + 4 = -2 + 4 = 2

Jonathan is planning a party at the skating rink. The cost for each person attending is 3.50 for sate rental and $5.00 for food.
Zina [86]

He can only invite 35 people

the cost per person = $3.50 + $5.00 = $8.50

dividing $300 by $8.50 determines the amount he can invite

\frac{300}{8.5} = 35.29411...

He can invite 35 people at a cost of $8.50 × 35 = $297.50
