Question

4. Given the linear equation y = x – 7, find the y-coordinates of the points (-2, ), (7, ), and (2, ). Please show all of your work. Plot these points and graph the linear equation

Answer 1

replace x by -2 and see what you get for y. etc.
so the first one is
\[y=-2-7=-9\] and the coordinate is therefore
\[(-2,-9)\]

Answer 2

for x = 7 write
\[y=7-7=0\] so you have
\[(7,0)\] can you do the last one?

Answer 3

how do you plot them on a graph

Answer 4

how did you get the 7-7

Answer 5

y=2-7=-5
=2,-5
