Just plug numbers into the m and b
anonymous
  • anonymous
ok hun that is easier sad than done never done this and dont know how to do it :(
anonymous

ummmmm just like any two numbers ?
anonymous
  • anonymous
yeah any!
anonymous
  • anonymous
Your favorite numbers if you want.
anonymous
  • anonymous
7 and 2
anonymous
  • anonymous
Ok, then lets m = 7 and b = 2.
anonymous
  • anonymous
so, \[y=7x+2\]
anonymous
  • anonymous
ok now how would I work that ?
anonymous
  • anonymous
You mean, how do you solve the equation?
anonymous
  • anonymous
yes
anonymous
  • anonymous
You can solve it by graphing or doing algebra.
anonymous
  • anonymous
Do you know how to graph that equation?
anonymous
  • anonymous
yes I kind of got how to do that part
anonymous
  • anonymous
Well I you graph the equation just look at the point where the line crosses the x-axis.
anonymous
  • anonymous
it crosses the x-axis at some value of x. That "some value of x" is the solution of the equation.
anonymous
  • anonymous
ok can you help me out with this question? Create a linear equation which requires two steps to solve
anonymous
  • anonymous
You already have it:
anonymous
  • anonymous
\[7x+2=0\]
anonymous
  • anonymous
step 1:\[7x=-2\]
anonymous
  • anonymous
step 2: \[x = -\frac{2}{7}\]
anonymous
  • 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.
anonymous
  • anonymous
You need to do the same, plug values into the A, B, and C. Can you do that?
anonymous
  • anonymous
so like this 2a+4b=c ?right
anonymous
  • anonymous
Not exactly, but you are close. I meant plug values into the A, B, C, for example: \[2x+4y=4\]
anonymous
  • anonymous
ok now can you walk me through trying to solve that please?
anonymous
  • anonymous
First, do you know what it means to solve an equation?
anonymous
  • anonymous
kind of but it is all kind of new to me I never went to high school I did home schooling
