To find y = mx + b you need to determine the slope. To find slope use the formula
m = y2 - y1 / x2 - x1

Use two points on the graph such as (4, 100) and (12, 300)

Now plug it into the formula

m = 300 - 100 / 12 - 4

m = 200 / 8

m = 25

Now we know the slope, but we need to find the y-intercept.

y = mx + b

y = 25x + b

Substitute one of the points (4, 100) as the y value and x value to find b, the y intercept

100 = 25(4) + b

100 = 100+ b

100 - 100 = b

0 = b

Now plug in your formula

Y = 25x + 0

y = 25x

To find the height of a pole, a surveyor moves 120 feet away from the base of the pole and then, with a transit 8 feet tall, mea
Vikki [24]
Refer to the figure.
Let AB be the height of the pole; CD be the height of the transit; BC is the distance from the base of the pole to the transit.

Triangle ADE is a right triangle with angle D measuring 26 degrees. Using the tangent function, we have
     tan\:26^{\circ} =\frac{AE}{120}
So, 
     AE=120\:tan\:26^{\circ}
     AE=58.53\:

Therefore, the overall height of the pole is 
     AB=58.53+8=66.53\:feet

The height of the pole is 66.53 feet.

Apply the distribution
kicyunya [14]

Answer:

20(3m-2)

Step-by-step explanation:

In order to factor, you have to look for the greatest common factor, or what the biggest number could the two numbers be divided by.

In this case, both numbers can be divided by 20, and so we put the 20 outside of the parentheses.

This leaves with 3m and -2, which are left inside the parentheses.


Hope this helps :)
