What does it mean if the slope of a line is zero?
Will help you prepare for the material covered in the next section. Remember that a solution of an equation in two variables is an ordered pair. Let \(x=0\) and find a solution of \(x+2 y=0\)
Determine whether each statement "makes sense" or "does not make sense" and explain your reasoning. I use \(y=m x+b\) to write equations of lines passing through two points when neither contains the \(y\) -intercept.
Excited about the success of celebrity stamps, post office officials were rumored to have put forth a plan to institute two new types of thermometers. On these new scales, \(^{\circ} E\) represents degrees Elvis and \(^{\circ} M\) represents degrees Madonna. If it is known that \(40^{\circ} E=25^{\circ} M, 280^{\circ} E=125^{\circ} M\) and degrees Elvis is linearly related to degrees Madonna, write an equation expressing \(E\) in terms of \(M\).
Solve: \(3 x+5=4(2 x-3)+7\) (Section \(2.3,\) Example 3 )
