Answer:

3x-y=1 is in the form Ax+By=c

where A=3, B=-1, C=1

Step-by-step explanation:

we have to convert the equation y-5=3(x-2) to the form Ax + By = C.

the equation y-5=3(x-2) is in the form y-y_{1} =m(x-x_{1} )

which is the point slope form of a straight line in cartesian coordinate.

where m is the slope of the line and x_{1} ,y_{1} is the point through which the line is passing through.

therefore y-5=3(x-2) becomes y-5  = 3x-6

y-5+6=3x

y+1=3x

3x-y=1

this equation is in the form Ax+By=c

therefore comparing these two equations we get

A=3, B=-1, C=1

Determine the standard form of the equation of the line that passes through ( -5,0 ) ( 0 ,-9)
insens350 [35]

The general form for a line through two points (a,b) and (c,d) is

(c-a)(y-b)=(d-b)(x-a)

This is better than the slope forms because it works in the no slope case, as does the standard form.

If you haven't seen it before, it works because when (x,y)=(a,b) we get (c-a)(b-b)=(d-b)(a-a), both sides zero, and when (x,y)=(c,d) we get (c-a)(d-b)=(d-b)(c-a), clearly equal sides.

Here we have

(0 - -5)(y - 0) = (-9 - 0)(x - - 5)

5y = -9(x+5)

5y = -9x - 45

9x + 5y = -45

Ironically there are two standards for standard form; one with the constant alone on the right and one with the whole thing equal to zero.  I like the constant alone.

Answer: 9x + 5y = -45

Check:

We check each point is on the line

(-5,0)

9(-5) + 5(0) = -45, good

(0, -9)

9(0) + 5(-9) = -45, good again

Answer:

y = -1/4x -2

Step-by-step explanation:

the perpendicular slope would be -1/4

2 = -1/4 (-16) + b

b = -2

the equation should be y = -1/4x -2

None of the answers you typed could be correct.
