Question

Which inequality is equivalent to -y<7

Answer 1

y>-7

Explanation:

Graph y-7=0 |

Add 7 to both sides of the equation. Use the slope-intercept form to find the slope and y-intercept. The slope-intercept form is y=mx+b y = m x + b , where m m is the slope and b b is the y-intercept.

Answer 2

y > -7

Explanation:

Given negative of y is less than
`7`.

Multiplying by negative sides on both sides, the sign of the inequality is reversed.

Therefore,
`- y > 7 \implies y < - 7`

i.e., Value of
`y` is less than
`- 7`.

`\therefore - y < 7 \iff y > - 7`
