What is the slope of a line perpendicular to the line whose equation is y = 2x+5?
zubka84 [21]

Answer:

slope = - \frac{1}{2}

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

y = 2x + 5 is in this form with slope m = 2

Given a line with slope m then the slope of a line perpendicular to it is

m_{perpendicular} = - \frac{1}{m} = - \frac{1}{2}

Which equation represents the graphed function?
nadezda [96]

9514 1404 393

Answer:

  y = 1/4x -2

Step-by-step explanation:

The line rises one unit from -2 to -1 as x changes from 0 to 4. The slope is ...

  m = rise/run = 1/4

The y-intercept (b) is where the line crosses the y-axis, at y = -2.

The equation in slope-intercept form is ...

  y = mx + b

  y = 1/4x -2
