slope formula
you use that to find the slope :))
Answer:
x =10
Step-by-step explanation:
7(3x-1)-(x+5)
21x-7-x+5
20x-2=-52
x=20÷2
Answer: B
Step-by-step explanation:
It is $29.35 for each of the tickets that they buy for adults, so to figure out how much it is for all the adult tickets, it would be $29.35 times x. Same for the children tickets except it is times y and the amount of money is different.
Answer:
The answer to your question is letter B
Step-by-step explanation:
Process
1.- Get two points of each line
Line 1 Line 2
Point A (0, 2) (5, 7)
Point B (-4, 0) (0, -4)
2.- Find the slope of each line
Formula slope = m = (y2 - y1) / (x2 - x1)
Line 1 m = (7 - 2) / (5 - 0)
m = 5/5
m = 1
Line 2 m = (-4 - 0) / (0 + 4)
m = -4/4
m = -1
3.- Find the equation of the lines
Formula y - y1 = m(x - x1)
Line 1 y - 2 = 1(x - 0)
y - 2 = x
y = x + 2
Line 2 y + 4 = -1(x - 0)
y + 4 = -x
y = -x - 4
