y- YI= m (x-x1 ) Find an equation for the line that satisfies the given conditions. For problems 7-9, give your final answer in slope-intercept form. For problems 10-12, give your final answer in point-slope form. 7. Through (2, 1) and (1, 6) 10. x-intercept 1; y-intercept -3 8. Through (1, 3); slope 0 11. Through (2, -1); slope undefined 9. Through (1, -6); parallel to the line 12. Through (-1, -2); perpendicular to x+ 2y = 6 the line 2x + 5y + 8 = 0 e equations of two lines are given. Determine whether the lines are parallel, perpendicular, neither. Y = mx+b Y = mxtb 3. y = 2x + 3; 2y - 4 -5 =0 14. -3x + 4y = 4; 4x + 3y = 5
