BONUS: Write the equation of both lines given below, and then determine if the lines are parallel, perpendicular, or neither. Choose the correct
answer below.
Line 1: (1, 2) and (3, 1)
Line 2: (2.0) and (0, -1)
Line 1: y = 1/2 x + 2.5, Line 2: y = -2 x+1, Perpendicular
O y 1
Line 1: y = 2x + 1, Line 2: y = 2x - 1, Parallel
Line 1: y = -1/2 x + 3, Line 2: y = 2x-1, Perpendicular
Line 1: y = -1/2 x + 2.5, Line 2: y = 1/2 x - 1, Neither

correct choice is b

step-by-step explanation:

when you calculate the average rate of change of a function, you are finding the slope of the secant line between the two points. for the function the average rate of change from point to point can be calculated as

to find the average rate of change from day 2 to day 10, note that at day 2, 8 houses were sold, so a(2,8) and at day 10, 2 houses were sold, so b(10,2). thus,

whole number data type

step-by-step explanation:

as whole number type represents whole number

like 1, 2 ,3, 4

in other words the whole numbers are those numbers which cannot be written infraction.

since we can take days as a whole number i.e 1 day 2 day and we cannot write 1.2 day hence we will use whole number data type
