Answer:
y ∝ m and 1760 is a constant of proportionality.
Step-by-step explanation:
The relation between a distance in the yards (y) and the same distance in miles (m) is described by the equation y = 1760m.
So, the graph of the above equation passes through the origin(0,0) and it will be a straight line with a constant slope of 1760.
Therefore, a measurement in yards and a measurement in miles are in the relation of proportionality for the same distance.
Hence, y ∝ m and 1760 is a constant of proportionality. (Answer)
The slope of the line that contains the points (1 -1) and (-2 8) is -3
Step-by-step explanation:
Slope measures the steepness of a line. It is the ratio of vertical change to horizontal change. If the line increasing, the slope is positive and if the line is decreasing the slope is negative. If the line is horizontal slope is zero and if the line is vertical slope is undefined.
Equation for slope = (y2-y1)/(x2-x1)
here y2= 8
x2=-2
y1=-1
x1=1
Substituting the following,
slope = (8+1)/(-2-1)
=9/-3
=-3
hence the slope is -3
The second one would be true
Hope this helped.
