Question

can anyone help me with better understanding, How to solve linear equations by graphing? thanks!

Answer 1

do you have an attachment?

Answer 2

yea you need an attachment

Answer 3

the formula for linear equations is:
\(\color{blue}{y = mx + b}\)

Answer 4

http://www.mathwarehouse.com/algebra/linear_equation/slope-of-a-line.php <--- find the slope, and that slope will be "ratio" that y is to x
and where the lines "touches" or "intercepts" y, is the well, y-intercept

thus y = [slope] x + [y-intercept]

Answer 5

Attachment meaning?

Answer 6

picture to go with it

Answer 7

so how would I solve this linear equation
X+3y=8
x-4y=-6 by graping,

Answer 8

turn it into y = mx + b

Answer 9

so it would be (-x+8)

Answer 10

y=mx+b for this equation would be (-y)=(-x+8) right?

Answer 11

for x+3y=8? no, it's not -y

Answer 12

How do I find y=mx+b?

Answer 13

you want to move x to the right side. when you move it, the sign of it will change.

Answer 14

so it would change to y?
