What is an equation of the line that passes through the point (-4, -7) and is
1 answer:
Answer:
The answer is
<h2>Step-by-step explanation:
Equation of a line is y = mx + c
where
m is the slope
c is the y intercept
To find the equation of the line parallel to 3x - y = 14 we must first find the slope of 3x - y = 14.
So we have
y = 3x - 14
Comparing with the general equation above
Slope / m = 3
Since the lines are parallel their slope are also the same
So slope of parallel line = 3
Equation of the line using point ( - 4 , -7) and slope 3 is
<h3>We have the final answer as

The solution is (3 , 4) ⇒ 2nd answer
Step-by-step explanation:
The system of equations can be solved by:
- Elimination method
- Substitution method
The system of equations is:
y = 3 x - 5 ⇒ (1)
y = x + 3 ⇒ (2)
By using the substitution method substitute y in equation (2) by equation (1)
3 x - 5 = x + 3
Subtract x from both sides
x = 8
Divide both sides by
x = 3
substitute x by 3 in equation (1)
y = 3(3) - 5
y = 9 - 5
y = 4
The solution is (3 , 4)
