(5,-2)(-3,4)
slope = (4 - (-2) / (-3 - 5) = 6/-8 = - 3/4
y = mx + b
slope(m) = -3/4
use either of ur points...(5,-2)...x = 5 and y = -2
now we sub and find b, the y int
-2 = -3/4(5) + b
-2 = -15/4 + b
-2 + 15/4 = b
-8/4 + 15/4 = b
7/4 = b
so ur equation is : y = -3/4x + 7/4 <==

Step-by-step explanation:
Riyas score = ( correct answer × mark) + ( incorrect answer × mark lost )
= ( 3× 10) + ( -1 ×10 )
= 30 -10
=20
Answer:
B
Step-by-step explanation:
There are 6 values on the faces of a standard number cube, that is
1, 2, 3, 4, 5, 6
There are 4 values > 2, that is 3, 4, 5, 6
P( number > 2 ) =
=
→ B
Answer:
5
Step-by-step explanation:

Let f(x) = y
thus y =

switch the position of y and x in the equation

then solve for y in this case

∴ y=

Thus,
