slope = y2-y1 / x2-x1=
-1 -5 / 2 - -1 = -6/3 = -2
slope = -2
y intercept = y =mx +b
y = -2x +b
y=-2*-1 +b
5 = -2 +b
b = 5-2
b =3
y intercept = 3
Answer:
You can't add those two matrices as they do not have the same dimensions
Step-by-step explanation:
This also relates to subtraction as well (you need to have same dimensions)
Answer:
5/9
Step-by-step explanation:
9/9 minus 4/9 is 5/9
To find the size of the scale, we must divide its size by 20 (because the scale is 1:20). Doing that we get 150/20=7.5m=750cm. Hope this helps!
