Slope intercept form from a graph

1 answer:

8 0

The slope-intercept form of an equation is y = mx + b.

m = Δy/Δx
b = the point at which the line intersects the y axis (where x=0).
y = m(0) + b gives us the the point (0,b) on the line.

From a graph determine the slope of the line (rise over run) and the point and which the line intersects the graph, then fill in the values for m & b.

For example, you notice the slope is 2/1, and intersects y at (0,5). The equation is: y = 2x + 5

Answer:

1. 5.61 lb 2. 22,000 pounds 3. they are the same

Step-by-step explanation:

16 oz in a lb. 16 x 5 is 90. extra 7 is approx 0.61 of a pound. 2000 lb in a ton. 2000 x 2 = 20000 extra 2000. 22000 is bigger. 1000 grams in a kilo. 1000 x 7 = 7000. they are the same

3 different problems.

Answer:

see below

Step-by-step explanation:

b - 4 = 3

Add 4 to each side

b - 4+4 = 3+4

b = 7

-32 = 8w

Divide by 8

-32/8 = 8w/8

-4 = w

n/7 = -4

Multiply by 7 to each side

n/7 *7 = -4*7

n = -28

For this case we will define the following:
A, B: are the values of the triangle angles
a, b: are the values of the lengths of the sides opposite the angles A, B.
We then have to use the law of the sine:
$\frac{sinB}{b} = \frac{sinA}{a}$
Clearing the angle B we have:
$sinB = \frac{sinA}{a}*b$
$B = arcsin(\frac{sinA}{a}*b)$
Substituting values we have:
$B = arcsin(\frac{sin113}{200}*134)$
$B = 38.08$
Answer:
the following is true:
A. angle B=38.08 degrees
