Answer:
Slope = 0.65
y = 0.65x - 10.5
Step-by-step explanation:
Taking the points (-10,-17) and (-8,-15.7)
Slope = Change in y ÷ change in x
Change in y = -15.7 - -17 = 1.3
Change in x = -8 - -10 = 2
Slope = 1.3/2 = 0.65
Taking another point (x,y);
The slope intercept form is;
= 0.65
= 0.65
y + 17 = 0.65x + 6.5
y = 0.65x + 6.5 - 17
y = 0.65x - 10.5
Answer:
Trapezoid
Step-by-step explanation:
Given quadrilateral has vertices at points A(-2,-1), B(3,13), C(15,5) and D(13,-11).
Find slopes of lines AD and BC:
Since the slopes are the same, lines AD and BC are parallel.
Find slopes of lines ABD and CD:
Since the slopes are different, lines AB and CD are not parallel.
This means quadrilateral ABCD is trapezoid (two opposite sides - parallel and two another opposite sides - not parallel)
