Find the slope for (2, 150) and (4,130)
iris [78.8K]

Answer:

-10

Step-by-step explanation:

A slope's equation for 2 points on a coordinate plane is y² - y^1 ÷ x² - x^1

Note that the exponents aren't meaning powered, but just as a marking.

x1 is 2, x2 is 4, y1 is 150, y2 is 130

130-150 / 4-2     =     -20/2, so -10

Answer:

  slope = 2

Step-by-step explanation:

See the attachment for the markup.

It is usually convenient to choose places where the graph crosses grid intersections. Here, the graph crosses the x- and y-axes at integer values, so those points could be used, for example. We chose points away from the axes so that the rise and run lines could be seen more easily.

The graph has a rise/run of ...

  slope = rise/run = 2/1 = 2

The slope of the line is 2.
