Question

Given the linear equation y = 4x + 2, find the y-coordinates of the points (-2, ), (1, ), and (-3, ) Please show all of your work. Plot these points and graph the linear equation. Submit your graph

Answer 1

The graph is shown above (red line) with the given points. We get the y coords by putting x=-2, 1 and 3 in turn into the equation: y=4x+2: y=4(-2)+2=-8+2=-6; y=4(1)+2=4+2=6; y=4(-3)+2=-12+2=-10; giving us the points (-2,-6), (1,6) and (-3,-10) respectively.
