'ymx+b' is the formula of a straight line drawn on Cartesian coordinate system in which 'y' is the vertical axis and 'x' the horizontal axis. Such an equation is usually written ymx+b ('ymx+c' in the UK). m in this equation is 1/1 b in this equation is -10. Step 1 : Equation of a Straight Line 1.1 Solve y+x-10 0 Tiger recognizes that we have here an equation of a straight line.
The region that is to the left of the line $x = 5$ and above the line $y - x = 10$ satisfies both inequalities, so it is the solution set. The equation is the y intercept form y mx + b where m the slope think mountain ski slope. Since $(0, 0)$ satisfies the inequality $x 10$, shade on the side of the line $y - x = 10$ opposite from the origin. Observe that the origin is not on either line. Since each inequality is strict, draw dashed lines $x = 5$ and $y - x = 10$. The region where each inequality is satisfied is the solution set. If the inequality is satisfied at that point, shade the side of the line containing the point if the inequality is not satisfied at that point, shade the side of the line opposite from the point. To determine which region to shade for a given inequality, pick a point that is not on the line corresponding to that inequality. If the inequality is weak ($\leq$ or $\geq$), draw a solid line. If the inequality is strict ($$), draw a dashed line.
