a. Slope of WZ = -2.25; Slope of WX = 5
b. WZ = √97; WX = √41
c. WXYZ is not a <em>rectangle, rhombus, nor a square</em>. We can conclude that: <em>D. WXYZ is none of these</em>.
<h3>Slope of a Segment</h3>Slope = change in y/change in x
Given:
W(-1, 2), X(-5, 7), Y(-1, -2), and Z (3, -7)
a. Slope of WZ and slope of WX:
Slope of WZ = (-7 - 2)/(3 -(-1)) = -2.25
Slope of WX = (7 - 2)/(-1 -(-1)) = 5
b. Use distance formula, , to find WZ and WX:
c. The quadrilateral WXYZ have adjacent sides that are not perpendicular to each other and have different slopes and different lengths, so therefore, WXYZ is not a rectangle, rhombus, nor a square. We can conclude that: <em>D. WXYZ is none of these</em>.

Answer:
The equation of the line that goes through points (1,1) and (3,7) is
Step-by-step explanation:
Determine the equation of the line that goes through points (1,1) and (3,7)
We can write the equation of line in slope-intercept form where m is slope and b is y-intercept.
We need to find slope and y-intercept.
Finding Slope
Slope can be found using formula:
We have
Putting values and finding slope
We get Slope = 3
Finding y-intercept
y-intercept can be found using point (1,1) and slope m = 3
We get y-intercept b = -2
So, equation of line having slope m=3 and y-intercept b = -2 is:
The equation of the line that goes through points (1,1) and (3,7) is
