Question

i need help with this question..................

The slope of the line whose equation is x + 2y = 3 is


-1/2
-1
-2

Answer 1

y=mx+b

Answer 2

Make the equation look like this

Answer 3

do u understand?

Answer 4

the slope is -1/2

Answer 5

2y=3-x
2y=-x+3
y=-(1/2)X+(3/2)

Answer 6

m=-1/2

Answer 7

Determine the slope of the given line.
2y = x-3

y = (1/2)x - (3/2)
slope of the given line is 1/2

Therefore slope of any perpendicular line must be -2


Form of needed equation: y = mx + b
y = -7 when x = 4 and the slope is -2
Solve for "b":
-7 = -2*4 + b
b = 1

Equation:
y = -2x +1

Answer 8

so , it will be m=-1/2

Answer 9

@ryanvarghese12790 the given equation is not 2y=x-3, it is 2y = -X + 3

Answer 10

i don't know how y came up with -1/2

Answer 11

May I help you @khofer ?

Answer 12

Look :
If we want to have a standard form should be have y alone .
So have this :
y=mx+d
So y is alone means nothing is before or after that ...
So we have :
x + 2y = 3
2y=-x+3
But 2 is extra .. So delete it from this way ...:(Divided on 2)
y=-x/2+3/2
Got it ?:)
