What is the slope of the line through the points (–3, 5) and (4, 5)? undefined 0 2 –2
Kazeer [188]

Finding the slope using two points:

The formula for slope is

\frac{y_{2}-y_{1}}{x_{2}-x_{1}}

In this case you have the points (-3, 5) and (4, 5):

y_{2} =5\\y_{1} =5\\x_{2} =4\\x_{1} =-3

^^^Plug these numbers into the formula for slope...

\frac{5-5}{4 - (-3)}

\frac{0}{7}

0

^^^This is your slope

Hope this helped!

Help me answer please
fiasKO [112]

Answer:

25

Step-by-step explanation:

b=4x+1    h=x+1     A=175

A=bh

Substitute: 175=(4x+1)(x+1)

Expand: 175=4x^2+5x+1

Subtract 175

4x^2+5x-174=0

Solve w/quadratic formula

(-5 <u>+</u> sqrt(25+2784))/8

Simplify: x=6 or -29/4

Distance is positive, so x=6

4x+1=4*6+1=25
