The answer is p=2s+7. Two plants can be grown from each seed packet, and Erin already has seven plants so you add that to the equation as well.

What is the slope and the y-intercept of -1.7x-1.9y=5.8
Julli [10]

Answer:

The slope is -0.89 and the y-intercept is (0, -3.05).

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.

Convert the equation by rearranging the terms using inverse operations.

-1.7x - 1.9y = 5.8                                 Add 1.7x to both sides.

+1.7x                     +1.7x

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

       -1.9y = 5.8 + 1.7x                         Divide both sides by -1.9.

            y= - 0.89 x - 3.05

This is now in y=mx+b and m=-0.89 and b=-3.05.

The slope is -0.89 and the y-intercept is (0, -3.05).
