(-5,-7) you always have to start with the x axis which will give you the x coordinate. The y axis gives you -7 the x gives -5. (x,y)

I have to find the slope for 4. ASAP please help

Lorico [155]

Given:

The objective is to find the slope of the straight line.

Explanation:

The general equation to find the slope is,

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

Let's consider two coordinates from the graph.

$\begin{gathered} (x_1,y_1)=(0,0) \\ (x_2,y_2)=(-1,5) \end{gathered}$

On plugging the values in the equation of slope,

$\begin{gathered} m=\frac{5-0}{-1-0} \\ m=-5 \end{gathered}$

Hence, the slope of the straight line is -5.

I need help, I don't know how to do it.

Sindrei [870]

Answer:

Step-by-step explanation:

to solve this problem we can use the Pythagorean theorem

UT and TL are the legs, while LU is the hypotenuse

We have to find LU so we can proceed like this

x^2 + (x+1)^2 = LU^2

x^2 + x^2 + 1 + 2x = LU^2

2x^2 + 2x + 1 = LU^2

LU = +/- $\sqrt{2x^2+2x+1$

we have to take only the positive value because a length can’t be negative.

2x^2 + 2x + 1 is positive for every value of x, so the final answer is

$\sqrt{2x^2+2x+1}$
