Answer:
slope of r = -9/4
slope of Q = 4/9
Step-by-step explanation:
x1 y1 x2 y2
10 6 1 2
(Y2-Y1) (2)-(6)= -4 ΔY -4
(X2-X1) (1)-(10)= -9 ΔX -9
slope= 4/9

Area of the electronic board is 9000 cm2
Step-by-step explanation:
Write ratios to represent the unknown actual length and width of the display to the scale length and width of the display.
The Electronic board always seems like a rectangular shape
Length= scale÷Actual = 5/36 = 5×36 = 180cm

Width=scale÷Actual = 1/50 = 1×50 = 50cm

Area of Rectangle = legnth × width
= 180cm × 50cm = 9000 cm2

Area of the electronic board is 9000 cm2
