Q. What is the slope of the line?\newlinex+3y=10x+3y=10\newlineChoose 11 answer:\newline(A) 110\frac{1}{10}\newline(B) 13\frac{1}{3}\newline(C) 110-\frac{1}{10}\newline(D) 13-\frac{1}{3}
  1. Isolating the term with y: We start by subtracting xx from both sides of the equation to isolate the term with yy.\newlinex+3yx=10xx + 3y - x = 10 - x\newlineThis simplifies to:\newline3y=x+103y = -x + 10
  2. Solving for y: Next, we divide each term by 33 to solve for yy.\newline(3y)/3=(x)/3+10/3(3y) / 3 = (-x) / 3 + 10 / 3\newlineThis simplifies to:\newliney=(13)x+103y = -(\frac{1}{3})x + \frac{10}{3}
  3. Identifying the slope: Now that we have the equation in slope-intercept form, we can identify the slope. The coefficient of xx is the slope of the line. In this case, the coefficient of xx is (13)-\left(\frac{1}{3}\right).
  4. Identifying the slope: Now that we have the equation in slope-intercept form, we can identify the slope.\newlineThe coefficient of xx is the slope of the line.\newlineIn this case, the coefficient of xx is (13)-\left(\frac{1}{3}\right).Therefore, the slope of the line defined by the equation x+3y=10x + 3y = 10 is (13)-\left(\frac{1}{3}\right).
