Question

Which of the following is the standard form of the equation y = -3x + 4?

A. 3x - y = 4
C. 3x + y = 4
B. 3x + y = -4
D. 3x - y = -4​

Answer 1

3x + y = 4

Explanation:

The standard form of an equation can be written as: ax + by = c

The equation is currently written in slope-intercept form.

In order to turn it into standard form, we must have both x and y on one side of the equation. So...

y = -3x + 4 Add 3x to both sides

3x + y = 4

Therefore the standard form of the equation y = -3x + 4 is 3x + y = 4
