Answer:

G. y = \frac{1}{2} x  + 1

Step-by-step explanation:

\because \: line \: m \: is \: passing \: through \: the \:  \\ points \: (3, \: 2) \: and \: (4, \: 0) \\  \\ slope \: of \: line \: m =  \frac{0 - 2}{4 - 3}  =  \frac{ - 2}{1}  =  - 2 \\  \\  \because \: line \: l \perp \: line \: m \\  \\  \therefore \: slope \: of \: line \: l = -   \frac{  1}{slope \: of \: line \: m}  \\  \\  \therefore \: slope \: of \: line \: l = \frac{1}{2}  \\  \\ line \: l \: is \: passing \: through \: (6, \: 4) \\  \\ \therefore \:equation \: of \: line \: l \: in \: point \: slope \: \\  form \: is \: given \: as \\  \\ y - 4 =  \frac{1}{2} (x - 6) \\  \\ y  - 4=  \frac{1}{2} x - 3 \\  \\ y = \frac{1}{2} x - 3 + 4 \\  \\  \huge \red{ \boxed{y = \frac{1}{2} x  + 1}}

quester [9]

Answer:

y=-2x+5. (4,-3)

Step-by-step explanation:

1) What's being asked in other words is to write a function. So the initial point is (1,3). In x-axis, a translation movement can only be to the right or to the left. Similarly for y-axis the possible movements are shifting up or down. The question says, 3 units right for x-cordinate and 6 units down for y cordinate. So the final point of this translation would be (1+3,3-6) =(4,-3)

2) To write a linear function we need to find out the slope:

m=\frac{-3-3}{4-1}=m=\frac{-6}{3} m=-2

3=1(-2)+b\\3+2=b\\ b=5\\ \\-3=4(-2)+b\\ b=8-3\\ b=5

y=-2x+5

<u>Proof:</u>

x=1

y=-2(1)+5

y=3 Then (1,3)

x=4

y=-2(4)+5

y=-8+5

y=-3 Then (4,-3)
