Slope intercept is y=mx+b
m=slope
slope if found by
m=(y1-y2)/(x1-x2)
(x,y)
(-1,-2) and
(1,2)
x1=-1
y1=-2
x2=1
y2=2
m=(-1-1)/(-2-2)
m=-2/-4
m=1/2
y=1/2x+b
solve fo by subsituting one x value
(1,2)
x=1
y=2
2=1/2(1)+b
2=1/2+b
subtract 1/2
3/2=b
equation is
y=1/2x+3/2
Answer:
44º
44º
136º
22º
Step-by-step explanation:
If you want i can explain in the comments.
It seems to me this just wants you to add the 3 equations.
2m + 2n +5p
No error - A and B are completely right, and using the subtraction law D is right
The answer is B i did this before hope this helps
