Take the opposite recporical of the slope give...so the so that would be. 2.

when two lines are perpendicular, switch the numerator and denominator of the given slope, add a negative sign in the front, you will have the slope of the other line.
if the slope is an integer, for example 3, it is the same as 3/1, the slope of the perpendicular line is then negative 1/3, (-1/3)
in this case, the slope of CD is -(-2/1)=2

Can someone find the points/coordinates of this graph?

BigorU [14]

Answer:

The x represents the value of the point on the x axis or the horizontal line, and the y represents the vertical line. Now, lets solve for the first point. We can first see that it only moves to the left by two from zero, which is basically -2. So, right now we have (-2,y). We then look for the y in which we see that it is down -6 from zero, so it will be (-2,-6). Time to look for the second point. We should get (2,-3). Now, with these two points, it is time to find the slope intercept form.

A line that passes through the point (4, 2) and has the slope of -3/2

mash [69]

The answer is: y = -3/2 x + 8

Graph:

To find the answer we use the formula;

y-y1 = M1 (x - x1)

y-2 = -3/2 (x-4)

When fully solved: the answer is:
y = -3/2 x + 8

Please answer thanks!

If you divide 13 by 3 you get 4 1/3 then you subtract 25 by 4 1/3 to get 20 2/3 so the answer is B
