Identify the shading and type of boundary for the graph of y ≥ 6x − 2 1)a broken line, shaded below the line 2)a broken line, shaded above the line 3)a solid line, shaded below the line 4)a solid line, shaded above the line
i think that it's 2) a broken line, shaded above the line
a broken line would just be > a solid line is used to indicate inclusiveness, like ≥
so it;s probably 3 than. a solid line shaded below the line
because it's -2 right?
no that's just the y-intercept of the equation. you shade where the inequality suggests. in this case it's greater than, so everything ABOVE this equation (including this equation) is valid.
ugh i feel silly! thankyou though!
so for y ≤ 7 − 2x it would be a broken line, shaded above the line right?
no. it is less than, which means below. a broken line is for < and >, and solid line is for ≥ and ≤
ah! i really do get it now. thankyou :)
