Graphing and solving inequalities quick check
WebIf you graph the line through these two points, You will see that you get the vertical line going through the point (1,0). So now since the inequality is > and not greater than or equal to, you use a dashed vertical line. And not for what you asked. WebSep 27, 2024 · To graph an inequality: Graph the related boundary line. Replace the <, >, ≤ or ≥ sign in the inequality with = to find the equation of the boundary line. Identify at least one ordered pair on either side of the …

WebYou will create tables to find equations, apply your knowledge of graphing lines by finding the intercepts and plotting points, interpret slope, understand inequalities graphically, and solve equations. Web5x-y >= 5 and y=5 If you change the first equation to slope y-intercept form 5x-y >= 5 add y to both sides 5x-y+y >= 5+y The y-y = 0 and disappears 5x >= 5+y And subtract 5 from both sides 5x-5 >= y Now reverse the sides and reverse the sign y <= 5x-5 So we now the slope is 5 and y-intercept is (0,-5)
Web Step 1 We must solve for one unknown in one equation. We can choose either x or y in either the first or second equation. Step 2 Substitute the value of x into the other equation.
