Consider the following linear equation.y = -1-Step 1 of 2: Determine the slope and the y-intercept (entered as an ordered pair)
Dmitriy789 [7]

Recall that a slope-intercept form of a linear equation is

\begin{gathered} y=mx+b \\ \text{where} \\ m\text{ is the slope} \\ b\text{ is the y-intercept} \end{gathered}

Rearrange the given so that it follows that slope intercept form

\begin{gathered} y=-1-\frac{2}{5}x\Longrightarrow y=-\frac{2}{5}x-1 \\  \\ \text{Now that it is in the slope intercept form} \\ y=-\frac{2}{5}x-1 \\ \text{we can determine that the slope is } \\ m=-\frac{2}{5} \\ \text{and the y-intercept is} \\ b=-1 \end{gathered}

The y-intercept is the value for which the linear function crosses the y-axis, this is when the value of x is equal to zero. The ordered pair therefore of the y-intercept is (0,-1).

Find the slope of the line that passes through the coordinates (3,-6) and (-9,2)
JulsSmile [24]

9514 1404 393

Answer:

  -2/3

Step-by-step explanation:

The slope formula is useful for this.

  m = (y2 -y1)/(x2 -x1)

  m = (2 -(-6))/(-9 -3) = 8/-12

  m = -2/3

The slope of the line is -2/3.

__

The graph shows the two points and a line with a slope of -2/3.
