Answer:

-4/5 and -9/5

Step-by-step explanation:

To find the slope of the graph we need to simply the given equation. We can do that by taking the x term to the left of the equation:

4\cdot{x}+5\cdot{y}=-9

5\cdot{y}=-9-4\cdot{x}

We can divide the whole expression by 5 to obtain the complete form of a straight line which is y=mx+c. Where m is the slope and c the y-intercept.

y=-9/5-(4/5)\cdot{x}

The slope is -4/5 and the y-intercept is -9/5

4x + 5y = 9
5y = -4x + 9
y = -4/5x + 9/5......slope intercept form (y = mx + b)

In y = mx + b form, which is what this equation is in now, the slope is in the m position and the y int is in the b position

y = mx + b
y = -4/5x + 9/5
so ur slope(m) = -4/5 and ur y int (b) = 9/5

Find the product 20*9*15 tell which property you used
alukav5142 [94]
Okay so first what you would have to do is to read the question carefully and understand it because if you don't read the question, well the thing is you could get it wrong. and so first see what the question is and then understand it and once you'd understand it, solve it. So what you would have to do is tell the property is using and think about how the question is written and think of the properties you have studied. Well you might as well notice that its the associative property because if you don't have parenthesis around your problem, it wouldn't be as organized as it should be because if you don't follow the Associative Property, it could confuse you. And so the answer to this problem would be a more good or sensible answer because you used the properties to help you and so your final answer to this problem would be 2,700 as your final answer and keep in mind that if you use properties it would be a much easier problem to solve. And so thank for your question and have a blessed day and May God bless you and I hope this helped you out with your question you asked and so thank you again and so see you again. Bye !!!
