Answer: Y intercept: 5 The slope of the line is: 2

Step-by-step explanation:

Y=mx+b is y-intercept form

So you have to solve this equation for y.

This looks like:

-2x+y=5

+2x      +2x

y=2x+5

The perimeter of a rectangle can be found using the equation P = 2L + 2W, where P is the perimeter, L is the length, and
a_sh-v [17]

Answer:

No, that is not possible

Explanation:

P = 2L + 2W

Insert numbers into equation

p=(2)(20)+(2)(11)

Step 1: Simplify both sides of the equation.

p=(2)(20)+(2)(11)

p=40+22

p=(40+22)(Combine Like Terms)

p=62

p=62

The perimeter is 62, not 64, so the perimeter can't be 64 if the length 20 and the width is 11.

Use function notation to write the equation of the line
blondinia [14]

f(x)=mx+b\to y=mx+b

We have two points:

(-3,\ 0);\ (-4,\ 7)

The point slope form of the line:

y-y_1=m(x-x_1)\\\\m=\dfrac{y_2-y_1}{x_2-x_1}

Substitute

m=\dfrac{7-0}{-4-(-3)}=\dfrac{7}{-1}=-7

y-0=-7(x-(-3))\\\\y=-7(x+3)\\\\y=-7x-21

Answer:

f(x)=-7x-21
