Answer:
Step-by-step explanation:
6) Slope = 5
(5 , 40) ; m =5
y - y1 = m(x -x1)
y - 40 = 5 (x - 5)
y -40 = 5x - 25
y = 5x - 25 + 40
y = 5x + 15
7) slope = 2
m =2 ; (-2 , 0)
y - y1 = m(x -x1)
y - 0 = 2(x -[-2])
y = 2(x +2)
y = 2x +4
8) D) It takes 6 miles to travel a mile
Because Line 1 is parallel to Line 2, angle "a" should also be 46 degrees. b is complementary so it would be 180-46=134(degrees).
The solution of the given system of equation is x = -3 and y = 4 respectively.
<h3>What is a system of linear equations?</h3>
A system of linear equations can be defined as a number of equations needed to solve the equations. For n number of variables n number of equations are required.
The given system of equations is as,
y = 4x + 16 (1)
y = −2x − 2 (2)
In order to solve them, substitute equation (2) into (1) as follows,
4x + 16 = −2x − 2
=> 4x + 2x = -2 - 16
=> 6x = -18
=> x = -3
Then, y = -2 × -3 - 2 = 4
Hence, the solution of the given system of equation is x = -3 and y = 4.
