The straight lines passing through these pairs of points (2, 5) and (4, 7) ,(−4, 2) and (1, 7) are, a) parallel
b) perpendicular
c) intersecting
d) non of these

The line passes (2, 5) and (4, 7) has slope:

S = (7 - 5)/(4 - 2) = 2/2 = 1

The line passes (1, 7) and (-4, 2) has slope:

S = (2 - 7)/(-4 - 4) = 5/-5 = -1

The multiplication of two slope is  1 x (-1) = -1

=> Two lines are perpendicular

Hope this helps!

part b

it is a function because for every x value there is only one y value

part   c

for every x value there is only one y value

step-by-step explanation:

f(x)=2x^2 -1 

translation is a function transformation that transform the function in a way of translating. by translating the function its graph is moved  up an down. moving the function f(x) 2 units to the left will be the new function g(x) with the equation: g(x)=f(x+2)=2(x+2)^2 -1
