Find the coordinates of all the points by preforming the given transformation. Plot the point (2,2) on the coordinate grid. Plot the points as you go, connecting each image to its pre image using a line segment. Finally connect the image from #15 to the original point (2,2)
(0,-3) see attached graph
step-by-step explanation:
a. to solve the system, graph the two equations.
x = y+3 becomes y=x-3 has m=1/1 and b=-3. start at (0,-3) on the y-axis and plot a point. then move up 1 unit and 1 unit to the right. plot a point and connect.
y=-4x+3 has m =-4/1 and b=-3. start at (0,-3) on the y-axis and plot a point. then move down four units and to the right 1 unit. plot a point and connect.
the solution is the point (x,y) where the two lines intersect. by the graph below it is (0,-3).
b. to solve by substitution, substitute y = -4x-3 into x= y+3
x= (-4x-3) +3
x=-4x
5x=0
x=0
now substitute x = 0 back in to find y.
y= -4(0)-3
y=0-3
y=-3
solution is (0,-3)
c. use elimination by adding the equations together.
x-y=3
4x+y=-3
5x=0
x=0
then substitute into one equation to find y.
y=-4(0)-3
y=-3
