Answer:
Slope (m) = 
Step-by-step explanation:

X = 4 – 1 = 3
Y = 4 – 2 = 2

Equation of the line:
y = 0.66666666666667x + 1.3333333333333
or

When x=0, y = 1.3333333333333
When y=0, x = -2
Answer:
= 8sqrt2
Step-by-step explanation:
Area of a trapezium is given by the formula;
1/2(a+b)h
;
Where a and b are the parallel sides and h is the perpendicular height.
a = 3 cm, b= 5 cm
To get; h, we use the Pythagoras theorem;
h² = 3² - 1²
h² = 8
h = √8
= √4√2
= 2√2
Thus;
Area = 1/2(3 +5) 2√2
= 1/2 ×8 × 2√2
<u> = 8√2 cm² or 8sqrt2 cm²</u>
