2. A line goes through the points (8, 9) and (-2, 4).
Scrat [10]

Answer:

Step-by-step explanation:

A line goes through the points (-2, 4) and (8, 9).  We see that x increases by 10 and y increases by 5.

Thus, the slope of this line is m = rise / run = 5/10 = 1/2    (the slope)

Starting with the point slope equation y - k = m(x - h) and substituting 9 for y, 8 for x and 1/2 for m, we get:

y - 9 = (1/2)(x - 8)   (point-slope form)

y       = (1/2)x + 5     (slope-intercept form)

Answer:<em> (-2.1)(3p)+(-2.1)(-5)</em>

Step-by-step explanation:

<em>Due to the -2.1 being on the outside of the parenthesis' you will distribute it into the (3p-5)</em>

<em>The first part will be (-2.1)(3p)</em>

<em>The next part will be +(-2.1)-5)</em>

<em>This is "+" due to a negative being multiplied by a negative.</em>

<em>(-2.1)(3p)+(-2.1)(-5)</em>
