Question

A line, y = mx + b, passes through the point (1,6) and is parallel to y=4x+ 6. What is the value of b?

2. The table below shows the hours, x, spent working on a new road and the distance, y, of finished road.

Time (hours) Distance (miles)
50 1.5
200 6
350 10.5
400 12
650 19.5
What is the slope of the line that fits these data points?
A. 3400
B. 3100
C. 335
D. 3

Answer 1

There is a space between the time and distance, I put them differently, and when I submitted the question, they posted as that. Sorry! For any confusion!

Answer 2

#1, Since the new line is to be parallel to the given line, it must also have a slope of 4
So it must look like y = 4x + b
sub in your given point, find b, and rewrite my equation.

#2. None of the given choices make sense for your given data
the slope between any two points in the given data is .03

Answer 3

thank you!
