Answer:
b = -4 and 0
Step-by-step explanation:
Using the distance formula
D = √(x2-x1)² + (y2-y1)²
√8 = √(b-2)² + (3-1)²
√8 = √(b-2)² + 2²
Square both sides
8 = (b-2)² + 2²
8 = (b-2)² + 4
8 - 4 = (b-2)²
4 = (b-2)²
Square root both sides
±√4 = b- 2
±2 = b - 2
b = -2 - 2 and b = -2 + 2
b = -4 and 0
This gives the values of b

Answer:
Step-by-step explanation:
Slope-intercept form is represented by the formula . So, to place the given equation in slope-intercept form, isolate the y on the left side and arrange the terms in that matching order. Remember, whatever you do to one side, do to the other:
So, the slope-intercept form is .

Answer:
Step-by-step explanation:
Ticket price for 2 adults = 55 * 2 = £ 110
Ticket price for 2 children = 45 * 2 = £ 90
Ticket price for 2 children & 2 adult = 110 + 90 = £ 200
Ticket price for family = £ 170
Discount = 200 - 170 = £ 30
Percentage of discount = (30/200) *100
= 15 %
