20. angle- side- angle
step-by-step explanation:
y < -3
-3y - 2 > 7
-3y -2 + 2 > 7+2
-3y > 9
-3y/-3 < 9/-3 (change the inequality sign when multiplying or dividing by a negative number)
correct choice is a
the equation of the line passing through the points and is
thus, the equation of the line that passes through the points (0, -6) and (-3, 0) is
