K is the slope of the line formed by connecting the points.
Use slope formula:
$\frac{y_2 - y_1}{x_2 - x_1}$
where the 2 points are the end points of the line (First and last going Left to right)
$(x_1,y_1) = (2,7) \\ (x_2,y_2) = (8,28)$
Substitute into slope formula
$k= \frac{28-7}{8-2} = \frac{21}{6} = \frac{7}{2}$
You can check if this is correct by going back to graph and going "up 7" and "over 2" to get from one point to the next.

How do you do this? conculsion statements.

Hi,
The conclusion should be letter B, if Karl runs 1mi, then he runs 5280 ft. In fact, that option is the only one in which you combine the information you have to get a conclusion.

x - 27 = 62 → ( add 27 to both sides )

x - 27 + 27 = 62 + 27

x = 89

drag first box then box with x = 89

Using point slope form determine the equation of a line that is perpendicular to the line y=3x+4 and passes through point (6,-3)

siniylev [52]

I'm not gonna use point-slope form but I will tell you the equation in slope-intersect form. Perpendicular means that the slopes of the 2 equations have to be opposite reciprocals. That means if one is 2, the other slope has to be -1/2. Since the slope is 3, the slope of the equation you are making is -1/3. using desmos.com, I found out that the y-intercept has to be -1, so the equation is y=-1/3x-1

Can anybody graph y= —2x + 5.

Naddik [55]

Answer:

The y-intercept is 5 so that is where it will start then just keep going down by 2 since the slope is (-2)
