A line passes through the points (–3, –4) and (6, 2). What number is the x-intercept?
LuckyWell [14K]

Answer:

<h2>D. 3</h2>

Step-by-step explanation:

\bold{METHOD\ 1}

\text{The formula of a slope:}\\\\m=\dfrac{y_2-y_1}{x_2-x_1}\\\\\text{x-intercept:}\ (x,\ 0).\\\\\text{Susbtitute the coordinates of the points to the formula of a slope}\\\\(-3,\ -4),\ (6,\ 2),\ (x,\ 0):\\\\m=\dfrac{2-(-4)}{6-(-3)}=\dfrac{2+4}{6+3}=\dfrac{6}{9}=\dfrac{6:3}{9:3}=\dfrac{2}{3}\\\\m=\dfrac{0-2}{x-6}=\dfrac{-2}{x-6}\\\\\text{Therefore we have the equation:}\\\\\dfrac{-2}{x-6}=\dfrac{2}{3}\qquad\text{cross multiply}\\\\2(x-6)=(-2)(3)\\\\2(x-6)=-6\qquad\text{divide both sides by 2}\\\\x-6=-3\qquad\text{add 6 to both sides}\\\\x=3

\bold{METHOD\ 2}\\\\\text{Look at the picture.}

Mark points in the coordinate system.

Lead a line through these points.

Over [174]

Answer:

<u>Population : all the steaks Tessa can cook</u>

<u>Parameter : minimum internal temperature of 160 degrees Fahrenheit</u>

<u>Sample : two random thermometer readings</u>

<u>Statistic : minimum sample reading of 165 degrees Fahrenheit</u>

Step-by-step explanation:

Let's recall the definitions of these statistical concepts and match it with the information that were provided to us:

  • Populations can be the complete set of all similar items that exist, in our case, all the steaks that Tessa can cook.
  • Parameter is is a value that describes a characteristic of an entire population, such as the minimum temperature of the steaks Tessa is cooking in Fahrenheit degrees.
  • Sample is a subset of the population, in our case, the two random readings of the thermometer Tessa did.
  • Statistic is a characteristic of a sample, for our problem, it's the minimum reading of 165 degrees Fahrenheit.
