C+ 9 - 3( c - 10) > 1solve the inequality show steps

c + 9 - 3(c - 10) > 1

We're going to treat this like a regular algebraic equation, thus most algebraic rules and properties apply.

First, apply distributive property.

c + 9 - 3c + 30 > 1 (two - signs cancel out, creating a + sign.)

Combine like terms.

-2c + 39 > 1

Subtract 39 from both sides.

-2c > -38

Divide both sides by -2.

c < 19 (Because we're dividing by a negative number, the sign gets swapped.)

y= 2x+7

changed to y= 5x +7

as slope is increased from 2 to 5

therefore it would be less steeper

so, option d) is correct
