Step-by-step explanation:

The slope of the line passing through two points is given by,

$\frac{y2 - y1}{x2 - x1}$

13)

$\frac{(0 - y)}{(0 - 2)} = (\frac{ - 3}{2} )$

$\frac{ - y}{ - 2} = \frac{ - 3}{2}$

$y = - 3$

option D

14)

$\frac{ ( - 3 - y)}{(1 + 5)} = \frac{ - 1}{6}$

$\frac{ - 3 - y}{6} = \frac{ - 1}{6}$

$- 3 - y = - 1$

$- y = - 1 + 3 = 2$

$y = - 2$

option C

15)

$\frac{(y - 4)}{( - 5 + 1)} = \frac{1}{4}$

$\frac{y - 4}{ - 4} = \frac{1}{4}$

$- y + 4 = 1$

$- y = 1 - 4 = - 3$

$y = 3$

option B

16)

$\frac{(y + 3)}{( - 4 - 3)} = \frac{ - 3}{7}$

$- (y + 3) = - 3$

$y = 3 - 3 = 0$

option C

Calculate the area of the given quadrilaterals.

nadya68 [22]

Answer:

dissect the trapezium into a square and triangle. since the triangle is a right angled one the base is 17-7=10cm

the height is found using Pythagorean theorem to be 24cm i.e 26²=x²+10²,x=√(676-100),x=√576,x=24cn

area of trapezium is (1/2)(a+b)h

a is the shorter side and b the longer side

(1/2)*(7+17)24

=288cm²
