The given line passes through the points (0, -3) and (2, 3).

rodikova [14]

Answer:

y + 1 = 3( x + 1)

Step-by-step explanation:

We are asked to find the equation of the line in point-slope form

Step 1 : find the slope using the two points given

( 0 , -3) ( 2,3)

m = (y_2 - y_1) / (x _2 - x_1)

x_1 = 0

y_1 = -3

x_2 = 2

y_2 = 3

Insert the values into

m = 3 - (-3) / 2 - 0

m = 3 +3 / 2 - 0

= 6/2

= 3

Step 2: it was given in the question that the parallel to a given line and passes through ( -1 , -1)

Substitute the point into the equation

y - y_1 = m ( x - x _1)

m = 3

y - y_1 = 3 ( x - x_1)

x_1 = -1

y_1 = -1

y - (-1) = 3( x - (-1)

y +1 = 3 ( x + 1)

We don't need to open the bracket because we are asked to give the answer in a point-slope form

The equation of the line in point slope form is

y + 1 = 3( x + 1)

Continuing the previous problem, use the data points (1950, 0.75) and (1997, 5.15) to find the slope. Show all work necessary fo

Answer:

Slope is 0.094,

It represents the average rate of change.

Step-by-step explanation:

Since, the slope is the ratio of difference in y-coordinates and the difference in x-coordinates,

Also, in a order pair, first element shows the x-coordinate and second element shows the y-coordinate.

Here, the data points are (1950, 0.75) and (1997, 5.15),

Thus, the slope is,

$m=\frac{5.15-0.75}{1997-1950}$

$=\frac{4.4}{47}$

$=0.0936170212766$

$\approx 0.094$

Also, Slope represents the average rate of change.

Simple...

you have:

1.) Find the slope of the line using (-2,1) and (3,6)

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

$\frac{1-6}{-2-3} = \frac{-5}{-5}$

m=1 (slope)

2.)Tell whether the equation, 8y+3=5x+3, is a direct variation.

y= $\frac{5x}{8}$ (None)

3.)What is the slope and y-intercept of the graph of the equation y=2x+3?

Slope =2

y-intercept=3

C.

Thus, your answer.
