I've been teaching junior high math and physical education for 6 years in Alberta. I enjoy problem solving and helping students understand difficult math problems by breaking down large tasks into manageable steps. I could have used a service like Numerade while I was in school, so I'm excited and hopeful to add to your service.
In Exercises 41–44, determine whether the matrix is in row-echelon form. If it is, determine if it is also in reduced row-echelon form.$$\left[\begin{array}{llll}{1} & {0} & {1} & {0} \\ {0} & {1} & {0} & {2} \\ {0} & {0} & {1} & {0}\end{array}\right]$$
Find the point-slope form of the line passing through the given points. Use the first point as $\left(x_{1}, y_{1}\right) .$ Plot the points and graph the line by hand.$$(1,2),(3,-2)$$
