1. find the slope and the y-intercept of the equation 4x + 5y = -9. 2. find the slope and the y-intercept of the equation y − 3(x − 1) = 0. 3. if a line with a slope of -2 crosses the y-axis at (0, 3), what is the equation of the line?

1. The slope is -4/5 and the y-intercept is (0, -9/5).

2. The slope is 3 and the y-intercept is (0,3).

3. The line is y=-2x+3.

Step-by-step explanation:

To find the slope and y-intercept, convert the equation to y=mx+b where m=slope and b=y-intercept.

1. Convert the equation by rearranging the terms using inverse operations.

4x+5y=-9                             Subtract 4x to both sides.

-4x            -4x

------------------------------------

     5y= -9 -4x                       Divide both sides by 5.

       y= -9/5 - 4/5x

This is now in y=mx+b and m=-4/5 and b=-9/5.

2. Convert the equation by rearranging the terms using inverse operations.

y - 3(x-1)=0                             Add 3(x-1) to both sides.

   +3(x-1)      +3(x-1)

------------------------------------

            y = 3(x+1)                  Multiply 3 into the parenthesis.

            y = 3x+3

This is now in y=mx+b and m=3 and b=3.

3. Write the equation of a line using point slope form

.

This becomes

Here m =-2 and b=3.
