Question

Solve -3x + 1 > 4 and describe the graph of the solution.

x < -1; Open circle on -1, shading to the left

x < -1; Open circle on -1, shading to the right

x > -1; Open circle on -1, shading to the left

x > -1; Open circle on -1, shading to the righ

Answer 1

-3x + 1 > 4
-3x >4-1
-x>1
x<-1 (on multiplying both side the inequality sign changes )
so first mark -1 and then since it does not include equal sign with inequality so open circle
and < means towards left

Answer 2

x < -1; Open circle on -1, shading to the left
