We are given -5x + y = -3 and
-15x +3y = -7

We let y = 5x - 3

Then -15x + 3(5x - 3) = -7 or
-15x + 15x -9 = -7 which leads to
-9 = -7

This result means the lines do not intersect

The slope of the line whose equation is x-3y= 1 is<br> 0-3<br> -1/3<br> 0<br> 0<br> 1/3
insens350 [35]

x-3y= 1

The equation needs to be rewritten in proper Slope intercept form ( y = mx+b) where m is the slope and b is the y-intercept.

x-3y = 1

Subtract x from each side:

-3y = 1-x

Divide both sides by -3:

y = 1/-3 - x/-3

Simplify:

y = 1/3x - 1/3

The slope is 1/3

A graph that uses bars of various heights to represent the frequencies.
Sunny_sXe [5.5K]

A graph that uses bars of various heights to represent the frequencies is a <u>Histogram</u>

A histogram is an approximate representation of the distribution of numerical data. The term was first introduced by Karl Pearson. To construct a histogram, the first step is to "bin" (or "bucket") the range of values—that is, divide the entire range of values into a series of intervals—and then count how many values fall into each interval.

Therefore, a graph that uses bars of various heights to represent the frequencies is a <u>Histogram</u>
