Linear Equation 4(b-3) = -8                                  Distribut the 4 to the b and 3  4b-12 = -8                                       Add the 12 to both sides      +12    +12        4b = 4                                      Divide by 4 on both sides         4     4                                      The fours cancel out each           b = 1                                       other and b equals 1

Literal Equation Solve for R         V = IR                                       Divide both sides by I          I      I                                        The two I's cancel out              V  = R                                    R equals V divided by I             I

Y-intercept Form Solve for a line containing the origin and (-3,-5) and put it in y-intercept form. -5-0 = -5   =  5         Plug in the two points to find the slope -3-0    -3        3          The two negative numbers makes the slope                                   positive. Y= 5 x                       There is not a y-intercept because it        3                          crossed the y axis at 0.
