Identify the slope (m) and y-intercept (b) of the graph of each equation y=1/2x-7
Tamiku [17]

For this case we have that by definition, the equation of a line in the slope-intersection form is given by:

y = mx + b

Where:

m: It's the slope

b: It is the cut-off point with the y axis

We have the following equation:

y = \frac {1} {2} x-7

So:

m = \frac {1} {2}, the slope is positive

b = -7

For the graph, we place the point on the coordinate axis:

(x, y) :( 0, -7)\\(x, y) :( 1, - \frac {13} {2})

We draw the line!

The graphic is attached.

ANswer:

m = \frac {1} {2}, the slope is positive

b = -7

The area of the triangle is 1560 m2<br><br>True<br><br>False
ValentinkaMS [17]

Answer:

FALSE

Step-by-step explanation:

Area of triangle is given by formula :

Area\ =\ \frac{1}{2}\left(base\right)\left(Altitude\right)

From picture we see that Altitude = 60 m

Base = 52 + 71 = 123 m

Now plug these values into above formula:

Area\ =\ \frac{1}{2}\left(123\right)\left(60\right)

Area\ =\ \frac{1}{2}\left(15129\right)

Area\ =\ \frac{15129}{2}

Area\ =\ 7564.5

Which is different than given area 1560 m^2.

Hence answer is FALSE.
