if you put the points into the equation y2 - y1/x2 - x1 you'll end up with a zero in the denominator, which indicates a vertical slope. Basically the slope(m) is undefined
It's really easy to tell if your answer is going to be undefined if both the x values are the same (in this case they're both 9)
Answer:
i gave u the answer give brainliest
Step-by-step explanation:
Their slopes must be the same, but with different y-intercepts.
Here is an example: 2x + 1 and 2x + 4 are parallel lines.
Answer:
here i hope this help im not sure if a can find the exact answer your looking for but here is a formula
Answer:
It takes 70 minutes for 9 team members (painting 60 sq ft per minute) to paint a 4200 sq ft wall.
Step-by-step explanation:
4800 ÷ 20 = 240 sq ft per team member in 36 minutes
240 ÷ 36 = 6.67 sq ft per team member in 1 minute
6.67 × 9 = 60 sq ft per 9 team members in 1 minute
4200 ÷ 60 = 70 minutes (or 1 hour and 10 minutes)
