Answer:
Parallel line:

Perpendicular line:

Step-by-step explanation:
we are given equation 4x+5y=19
Firstly, we will solve for y

we can change it into y=mx+b form


so,

Parallel line:
we know that slope of two parallel lines are always same
so,

Let's assume parallel line passes through (1,1)
now, we can find equation of line

we can plug values

now, we can solve for y

Perpendicular line:
we know that slope of perpendicular line is -1/m
so, we get slope as

Let's assume perpendicular line passes through (2,2)
now, we can find equation of line

we can plug values

now, we can solve for y

The answer to the question is b

Answer:
C. 48
Step-by-step explanation:
first you solve 84 divided by 7 and your answer is 12 then you do 12x4 which is 48
Answer:
yes
Step-by-step explanation:
y=3x + 1
y = -x+5
Check if (1,4) solves the first equation
4 = 3(1)+1
4 = 3+1
4=4
This is true
Check the second equation
4 = -1+5
4=4
This is true
(1,4) is a solution to the system of equations
