Answer:
The equation of required line is y=2x+2.
Step-by-step explanation:
The slope intercept form of a line is
.... (1)
Where, m is slope and b is y-intercept.
The equation of given line EF is
.... (2)
From (1) and (2), we get
The slope of the line is 2 and y-intercept is 1.
The slope of parallel lines are same. So, the slope of required line is 2.
The line passes through the point (0,2). It means the y-intercept of the line is 2.
Substitute m=2 and b=2 in equation (1), to find the equation of required line.
Therefore the equation of required line is y=2x+2.
Answer: 10 hours
Step-by-step explanation:
Given
Slow fix auto charge $28 for parts and $48 per hour of labor
We work charge $59 for parts and $44.90 per hour of labor
Suppose both works for x hours
Cost of Slow fix=
Cost of We work=
When these costs are the same
