Answer:
Use the two-point form:
(y + 6) / (x - 8) = (-6 - 6) / (8 - 0)
(y + 6) / (x - 8) = -12 / 8
(y + 6) / (x - 8) = -1.5
y + 6 = -1.5x + 12
y = -1.5x + 6
Answer:
mkukuha mo sagot through formula
Step-by-step explanation:
What does the number m in y = mx + b
measure?
To find out, suppose (x1
, y1
) and (x2
, y2
) are two
points on the graph of y = mx + b.
Then y1
= mx1
+ b and y2
= mx2
+ b.
Use algebra to simplify y2 – y1
x2 – x1
And give a geometric interpretation.
Answer:
y2
– y1
x2
– x1
=
(mx2
+ b)– (mx1
+ b)
x2
– x1
=
mx2
– mx1
+ b – b
x2
– x1
=
mx2
– mx1
x2
– x1
=
m(x2
– x1
)
x2
– x1
distributive property
= m
No matter which points (x1
,y1
) and (x2
, y2
) are
chosen, m = y2
– y1
x2
– x1
.
But what does this mean?
Meaning of m = y2
– y1
x2
– x1
in y = mx + b
m =
y2
– y1
x2
– x1
is the
“rise” (i.e. y2
– y1
) over the
“run” (i.e. x2
– x1
) and
m is called the slope.
