Answer:

Step-by-step explanation:
The point-slope formula is
where we substitute a point (x,y) for
.
We have m=3 and (-1, 2). We input m and
.

Answer:
Step-by-step explanation:
by inspection.. just looking at the graph
slope = - 1/2 (called m )
Y-intercept is at 1
line equation is then
y= mx + b
y= -1/2x +1

Answer:
The length of the segment AB is 18.8 cm or 1.88 dm
Step-by-step explanation:
<u><em>The question in English is</em></u>
Points A, B and C are collinear in this order. Find the length of the segment: a) AB, if AC = 20 cm, BC = 0.12 dm
we have that
----> by Addition segment postulate
substitute the given values in centimeters
Remember that

so


solve for AB

Convert to dm

therefore
The length of the segment AB is 18.8 cm or 1.88 dm
