Answer:
1. c
2. b
3. c
4. a
5. b
6. c
7. c
Step-by-step explanation:
1. to check the congrency normally distance formula is used. if the distances/ length are equal we say that sides are congurent.
2. if the slope of two lines are equal then both the lines are parallel. if the product of the slopes of two lines equal to one then lines will be perpendicular.
3. diagonals bisect or not can be checked by using midpoint formula.
4. equilateral triangle if the distance of each side is equal so, distance formula can be used.
9 and 12 are slope-intercept form and 10 and 11 are point-slope form
Answer:
The answer is C. -2
Step-by-step explanation:
The formula for slope is referred to "rise over run". So in this case you rise 2 over one (2/1) That gives you 2. But since the line is going down is -2
Answer:
<h2>(8, -22)</h2>
Step-by-step explanation:
The slope-intercept form of an equation of a line:
m - slope
b - y-intercept
The formula of a slope:
First table:
(-4, 26), (0, 10) → b = 10
Second table:
(-4, 14), (0, 2) → b = 2
We have the system of equations:
