Q. What is the equation of the line that passes through the point (8,−4) (8,-4) and has a slope of −54 -\frac{5}{4} ?\newlineAnswer:
  1. Identify slope and point: Identify the slope mm and the point (x1,y1)(x_1, y_1) through which the line passes.\newlineThe slope mm is given as −54-\frac{5}{4}, and the point (x1,y1)(x_1, y_1) is (8,−4)(8, -4).
  2. Use point-slope form: Use the point-slope form of the equation of a line to plug in the values of the slope and the point.\newlineThe point-slope form is y−y1=m(x−x1)y - y_1 = m(x - x_1).\newlineSubstitute m=−54m = -\frac{5}{4}, x1=8x_1 = 8, and y1=−4y_1 = -4 into the equation to get y−(−4)=−54(x−8)y - (-4) = -\frac{5}{4}(x - 8).
  3. Simplify equation to slope-intercept form: Simplify the equation from the point-slope form to the slope-intercept form y=mx+by = mx + b.\newlineFirst, distribute the slope −54-\frac{5}{4} across (x−8)(x - 8):\newliney+4=−54x+54⋅8y + 4 = -\frac{5}{4}x + \frac{5}{4}\cdot8
  4. Isolate y: Continue simplifying the equation by multiplying (5)/(4)(5)/(4) by 88.\newliney+4=−(5)/(4)x+10y + 4 = -(5)/(4)x + 10
  5. Isolate y: Continue simplifying the equation by multiplying (5)/(4)(5)/(4) by 88.y+4=−(5)/(4)x+10y + 4 = -(5)/(4)x + 10Isolate y to get the equation in slope-intercept form. Subtract 44 from both sides of the equation:y=−(5)/(4)x+10−4y = -(5)/(4)x + 10 - 4y=−(5)/(4)x+6y = -(5)/(4)x + 6
