Im helping my sister with her math and I was able to help her with 50 out of 55 questions, if someone could help with a couple I would really be happy!
1- Select the ordered pairs in the table whose coordinates do NOT satisfy the equation x+2y=6 in the x column the #s are (top to bottom) 12, 6, 4, 8, -2. in the y column they are (top to bottom) 6, 8, 1, -1, 4. I selected x4, y1 and x8,y-1 but she thinks that is wrong.
2-Plot 2 ordered pairs whose coordinates satisfy the equation -2x - y = -1. What are the coordinates?
3- Complete the table to find 3 ordered pairs wose coordinates satisfy the equation x=3. x column (top to bottom) are BLANK (needs filled in) y column(top to bottom) -1.6, 48, 0.5.
4-which is true for the graph equation x=4?
a-the graph is a horizontal line
b-the graph is a vertical line
c-the graph is a line that pass through (0,0)
d-the graph is none of the above
I selected B but she thinks its wrong.
