What is the equation of the line in slope intercept form using these points?
deff fn [24]

Answer:

y = -x - 1

Step-by-step explanation:

1. The slope-intercept form of any linear equation is y = mx + b, where y = y-coordinate, m = slope, x = x-coordinate, and b = y-intercept.

2. To find the slope given two points, we can use the formula \frac{y_2-y_1}{x_2-x_1} and plug in the corresponding variable.

  • \frac{5-(-2)}{-6-1}
  • \frac{5+2}{-7}
  • \frac{7}{-7}
  • -1

3. Okay, so the slope is -1x or just -x. This means that the equation looks like this so far: y = -x + b

4. To find b, the y-intercept, we can take the equation of b = y_1 - m * x_1 and plug in the values!

  • b = -2-(-1)*1
  • b = -2 + 1 * 1
  • b = -1 * 1
  • b = -1

5. Now that we have our y-intercept and slope, let's plug in those values and find the equation!

  • y = -x - 1

Therefore, the equation of the line is y = -x - 1. I hope this helped you!

Charlie used a regression calculator to generate the equation f(x) = –0.15x + 20.1 for the ordered pairs (2, 15), (4, 21), (6, 2
aivan3 [116]
Answer: The r<span>-value for the linear function related to the ordered pairs is very close to zero, so it is not a good representation of the data. A quadratic model would better represent the data because there is a turning point within the data set. The data increases then decreases, which is what the graph of a quadratic does. </span>
