How do i put this in slope-intercept form. passes through 2,-2 and 4,-1

enot [183]

Answer:

$\large\boxed{y=\dfrac{1}{2}x-3}$

Step-by-step explanation:

The slope-intercept form of an equation of a line:

$y=mx+b$

m - slope

b - y-intercept

The formula of a slope:

$m=\dfrac{y_2-y_1}{x_2-x_1}$

We have two points (2, -2) and (4, -1).

Substitute:

$m=\dfrac{-1-(-2)}{4-2}=\dfrac{-1+2}{2}=\dfrac{1}{2}$

Put the value of a slope and the coordinates of the point (2, -2) to the equation of a line:

$-2=\dfrac{1}{2}(2)+b$

$-2=1+b$ subtract 1 from both sides

$-3=b\to b=-3$

Finally:

$y=\dfrac{1}{2}x-3$

Find the area of the given polygon.

zimovet [89]

9514 1404 393

Answer:

88 square inches

Step-by-step explanation:

The figure can be divided into two congruent trapezoids, each with bases 7 and 4 inches, and height 8 inches. Then the total area is ...

A = 2(1/2)(b1 +b2)h

A = (7 +4)(8) = 88 . . . . square inches

1/2 (x-4/5)=3/5

malfutka [58]

1/2x-2/5=3/5 (BTW I got 2/5 by reducing 4/10)
1/2x=7/5 (BTW I got 7/5 by moving 2/5 to the other side)
Then do 7/5 times 2 and you get 14/5

14/5
