Answer:

y = -1/2x + 1

Step-by-step explanation:

in order to find the slope, you use rise/run.

for example,the point on (-2,2) and the point on (-4,3) goes UP (rise) by 1, and goes ACROSS (run) by 2.

this means that the slope of the line is -1/2x.

next, you need to find the y-intercept.

the y-intercept is the point on the Y line on the graph.

for this line, that point is 1.

the y-int is 1.

y=mx+b

mx = slope

b = y-int

Find the slope between the two points: (9,9) and (12,15)

grandymaker [24]

The slope formula is $\frac{Y2-Y1}{X2-X1}$ . For the two points, $(x,y)$ . You can pick any of the Y and X from these two points, but only once. $\frac{9-15}{9-12}$ = $\frac{-6}{-3}$ = 2 or $\frac{15-9}{12-9}$ = $\frac{6}{3}$ = 2 and both will equal to. The answer for the slope is 2.

Answer:

3rd quadrant

Step-by-step explanation:

First we just convert the angle from radians to degrees
$\frac{31\pi radians }{6}*\frac{180degrees}{\pi radians} =\frac{31*180}{6} degrees=930degrees$
Now that's too big, all this means is if we start rotating from the positive y-axis in a circle we will cross the starting point 2 times, 2 full circles;
$930degrees-360degrees=570degrees\\570degrees-360degrees=210degrees$
Now in which quadrant it 210 degrees?
0 degrees to 90 degrees is 1st quadrant
90 degrees to 180 degrees is 2nd quadrant
180 degrees to 270 degrees is 3rd quadrant
270 degrees to 360 degrees is 4th quadrant
So our answer is the 3rd quadrant.
