Answer:
Step-by-step explanation:
The equation of the line in point-slope form is:
Where m is the slope and 
is a point of the line.
The slopes of two perpendicular lines are opposite reciprocal, then the other slope is:
m=
Substitute the slope and the given point into the equation, then you obtain:
Answer:
each pair of socks cost $2.49
Step-by-step explanation:
Eric spent $22.00, including sales tax on 2 jerseys and 3 pairs of socks. The jerseys cost $6.75 each and the total sales tax was $1.03. How much did each pair of socks cost?
Solution:
The total money spent was $22.00. 2 jerseys costing $6.75 each was bought, the total tax was $1.03. 3 pairs of socks was bought, Let S represent the cost for each pair of socks. The total money spent is the sum of the money spent on jersey, socks and tax. Hence:
2(6.75) + 3S + 1.03 = 22
13.5 + 3S + 1.03 = 22
14.53 + 3S = 22
3S = 22 - 14.53
3S = 7.47
S = 2.49
Hence each pair of socks cost $2.49
Answer:
start at the point (0,-2) and go up one and to the right three, keep going until you run out of room. then, draw a straight line through all the points :)
Step-by-step explanation:
hope this helped!
Answer:
B
Step-by-step explanation:
To find the slope m use any 2 ordered pairs from the table.
Calculate m using the slope formula
m = 
with (x₁, y₁ ) = (- 4, 11) and (x₂, y₂ ) = (2, - 1)
m = 
= 
= - 2 → B
I do not see anything wrong with it
