Answer:
slope (m) = -8.
Step-by-step explanation:
Slope-intercept form is y = mx + b, in which:
m = slope
b = y-intercept
x = (x , y)
y = (x , y)
~
With the given information on top, it means that -8 is your answer.

since we know those two triangles are similar then we can use proportions.
The shape of the block could be either a cylinder of a cone
Answer:
3.) 90°; perpendicular bisector; AB; 9; E, AB.
Step-by-step explanation:
∠BEC and ∠BED form a linear pair. This means their sum is 180°. Since we know that m∠BEC = 90°, this means that
m∠BED = 180-90 = 90°.
Since AE = AB and CD intersects AB at right angles, this means that CD is the perpendicular bisector of AB.
This means that AE = 1/2AB.
If AB = 18, then AE = 1/2(18) = 9.
