What is the equation of the line with slope of 1/2 , and which passes through the point

Levart [38]

Answer:

(y+5)=\frac{1}{2}(x-4) in point slope form

Step-by-step explanation:

The point slope form of a line is $(y-y_1)=m(x-x_1)$ where $x_1=4\\y_1=-5$ . We write

$(y--5)=m(x-4)\\(y+5)=m(x-4)$

We know m the slope is $\frac{1}{2}$ and we substitute.

$(y+5)=\frac{1}{2}(x-4)$

Solve the inequality 31<3x + 4

Kipish [7]

Answer:

x > 9

Step-by-step explanation:

31 < 3x + 4

Treat the < sign the same way you do with =

So first minus 4

31 < 3x + 4

-4 -4

27 < 3x

Divide both sides by 3

9 < x

If you want x on the other side just flip the symbol

x > 9
