Question

Which of the following is in Standard Form?

1. y - 6 = -3 (x +5)
2. y = -3 (x +5)
3. y = -3x +5
4. 3x + y = 5

Answer 1

Equation 4

Explanation:

Standard Form is:

`Ax+By=C`

Option 1 is in point-slope form.

Option 2 is an incomplete point slope equation.

`y-y_1=m(x-x_1)\\\\y-6=-3(x+5)`

Option 3 is in slope-intercept form.

`y=mx+b\\\\y=-3x+5`

This leaves us which option 4, which is in standard form.

`Ax+By=C\\\\3x+y=5`

Option 4 should be the correct answer.

Hope this helps.
