Answer:
Step-by-step explanation:
Slope = 2 and passes point (4,7)
The equation is y - y1 = m(x - x1)
And y1 = 7 while x1 = 4, m = 2
: - y - 7 = 2(x - 4)
y - 7 = 2x - 8
y = 2x - 8 + 7
y = 2x - 1 this is the equation
infinite set is the answer
4.75
original price (100%) → $19
discounted price ((100-75)%) = (25%) → 25% x $19 = $4.75
199
82+25=107
107+92= 199
