## anonymous 4 years ago can anyone help me solve this question PLEASE??? Create a linear equation in two variables in the form y = mx + b to graph using the slope intercept form

1. anonymous

Just plug numbers into the m and b

2. anonymous

ok hun that is easier sad than done never done this and dont know how to do it :(

3. anonymous

Can you tell me two numbers?

4. anonymous

ummmmm just like any two numbers ?

5. anonymous

yeah any!

6. anonymous

Your favorite numbers if you want.

7. anonymous

7 and 2

8. anonymous

Ok, then lets m = 7 and b = 2.

9. anonymous

so, $y=7x+2$

10. anonymous

ok now how would I work that ?

11. anonymous

You mean, how do you solve the equation?

12. anonymous

yes

13. anonymous

You can solve it by graphing or doing algebra.

14. anonymous

Do you know how to graph that equation?

15. anonymous

yes I kind of got how to do that part

16. anonymous

Well I you graph the equation just look at the point where the line crosses the x-axis.

17. anonymous

it crosses the x-axis at some value of x. That "some value of x" is the solution of the equation.

18. anonymous

ok can you help me out with this question? Create a linear equation which requires two steps to solve

19. anonymous

You already have it:

20. anonymous

$7x+2=0$

21. anonymous

step 1:$7x=-2$

22. anonymous

step 2: $x = -\frac{2}{7}$

23. anonymous

ok cool now the last one I need help with is . Create a linear equation in two variables in the form Ax + By = C to graph using the x- and y- intercept method.

24. anonymous

You need to do the same, plug values into the A, B, and C. Can you do that?

25. anonymous

so like this 2a+4b=c ?right

26. anonymous

Not exactly, but you are close. I meant plug values into the A, B, C, for example: $2x+4y=4$

27. anonymous

ok now can you walk me through trying to solve that please?

28. anonymous

First, do you know what it means to solve an equation?

29. anonymous

kind of but it is all kind of new to me I never went to high school I did home schooling
