Answer:
y=1/2x - 1/2
Step-by-step explanation:
Slope intercept form is y=mx+b
The m is the slope of the line and the b is the y-intercept.
You must first the slope. The formula of a slope is (y1-y2)/(x1-x2). In this example it is (-2-3)/(-9-1) which equals 1/2. By order of elimanation we can see that y=1/2x-1/2 is correct.
78- acute
144- obtuse
This is because anything less than 90 degrees is acute. Think of it as they are cute because they are tiny xD
=90 is right angel
And anything above 90 and below 360 is obtuse because it's fat xD
