Write the slope-intercept form of the equation of the line.

Mathematics
1 answer:
Semenov [28]3 years ago
8 0

Answer:

y = x + 2

Step-by-step explanation:

First, find the slope.

(y2 - y1 / x2 - x1)

I'm going to use (0,-2) and (2,0) as my points.

Find the slope.

(-2) - 0 / 0 - 2= -2 / -2 = 1

So the slope is 1.

Now find the y-intercept.

Y-intercept is 2.

Now substitute it into the slope-intercept form equation. (y = mx + b)

y = x + 2

3x+2y=8          

x=2y

3(2y)+2y=8

6y+2y=8

8y=8

y=1

x=2(1)

x=2

x-1=2-1

x-y=1

Find ST if S(-3, 10) and T(-2, 3)
FrozenT [24]

We have the following points and their coordinates:

\begin{gathered} S(-3,10), \\ T(-2,3). \end{gathered}

We must compute the distance ST between them.

The distance ST between the two points is given by:

ST=\sqrt[]{(x_S-x_T)^2+(y_S-y_T)^2_{}},

where (xS,yS) are the coordinates of the point S and (xT,yT) are the coordinates of the point T.

Replacing the coordinates of the points in the formula above, we find that:

\begin{gathered} ST=\sqrt[]{(-3_{}-(-2)_{})^2+(10_{}-3_{})^2_{}}, \\ ST=\sqrt[]{1^2+7^2}, \\ ST=\sqrt[]{50}\text{.} \end{gathered}

Answer: ST = √50
