2x - 3(x-1) = -1
2x -3x + 3 = -1
-1x + 3 = -1
-1x = -4
x = 4
y = 4 - 1
y = 3

Answer:
(y2-y1)/(x2-x1)
Step-by-step explanation:
Using two coordinates, you can just plug in the corresponding (x,y) coordinates and you will get the slope, which is the rate of change over an interval
Answer:
189sq.cm
Step-by-step explanation:
Area of a parallelogram = b×h
= 21× 9
= 189 cm^2
Slope of parallel line to this would be -1/3x
