What is the equation in slope-intercept form of the line that passes through the points (−26, −11) and (39, 34)?
Scrat [10]

The equation in slope-intercept form of the line passing through the given points is: C. y = \frac{9}{13}x + 7

<u>Given the following points:</u>

  • Points on the x-axis = (-26, 39)
  • Points on the y-axis = (-11, 34)

To find the equation in slope-intercept form of the line passing through the given points:

Mathematically, the equation of slope is calculated by using this:

Slope. \;m = \frac{Change \; in \; y \;axis}{Change \; in \; x \;axis} \\\\Slope. \;m = \frac{y_2 - y_1}{x_2 - x_1}

Substituting the given points, we have:

Slope. \;m  = \frac{34 - [-11]}{39 - (-26)}\\\\Slope. \;m  = \frac{34\; + \;11}{39 \;+ \; 26}\\\\Slope. \;m  = \frac{45}{65}\\\\Slope. \;m  = \frac{9}{13}

The standard form of an equation of line is given by the formula;

y = mx + b

Where:

  • x and y are the points.
  • m is the slope.
  • b is the intercept.

We would find the intercept:

-11 = \frac{9}{13}(-26) + b\\\\ -11 = -18 + b\\\\b = -11 + 18

Intercept, b = 7

The equation in slope-intercept form of the line is:

y = \frac{9}{13}x + 7

Last question sorry please forgive me
bagirrra123 [75]

Answer:

y is 1/3 less than x

Step-by-step explanation:

No need to Apologize my friend!! thats what we do here, ask all the questions you want. If you just compare the x part of the coordinate, to the y part of the coordinate, the answers obvious. for example, the first labeled point is (1 and 2/3, 1 and 1/3) the y part is 1/3 less than the x part. so y is 1/3 less than x
