If you eliminate obvious wrong answers you increase your chances of getting the question correct.
Notice the inequality signs are both "equal to" which means a solid boundary line. This means choice B and D can not be correct.
You can test a point that is exclusively in the shaded region of each graph.
x + 2y ≤ 4 -x -x solve for y by moving x term 2y ≤ -x + 4 ÷2 ÷2 divide both sides of the inequality by 2 y ≤ -1/2x + 2 ← plot 2 on y-axis then move down 1 and right 2 put 2nd point shade below the solid line
3x - y ≥ 2 when solved for y → y ≤ 3x - 2 (the inequality sign switched because in the process of solving for y I had to divide by a negative number)
plot -2 on the y-axis then move up 3 and to the right 1 put 2nd point shade below the line
the answer is choice A only graph where they have shaded below both lines...use the y-intercept as a guide for shading above or below the line... shading where numbers are greater than the y-intercept is shading above the line and shading where numbers are less then the y-intercept is shading below the line
a linear function has a infinite number of solutions because every time you multiply it by the square route the way you should and then multiply by seven your answer is all ways infinite
