How do you solve step by step (-10)+14+25+(-16)

jeyben [28]

(-10) + 14 + 25 + (-16) Add 14 and 25
(-10) + 39 + (-16) Change 39 + (-10) to 39 - 10
(-10) + 39 - 16 Subtract 16 from 39
(-10) + 23 Change (-10) + 23 to 23 - 10
23 - 10 Subtract 10 from 23
13

*Remember, you can rearrange expressions like this as long as each number keeps its sign. Notice that (-10) had its negative sign the whole time, even though we moved it around.

Using the slope and the y-intercept, graph the line represented by the following equation. Then select the correct graph. 3y = 2

Over [174]

First, let's write the given equation in slope-intercept form: y = mx + b

In slope-intercept form, the slope of the line is m, and the y-intercept is b. The slope is a measure of how steep the graph is at any point and is found by doing rise over run. This means the change in y values divided by the change in x values. Next, y-intercept is just where the graph crosses the y axis.

All we need to do to get the equation in slope-intercept form is to divide each term by 3. This will isolate the y.

$y= \frac{2}{3}x-2$

As you can see, the slope of the line is 2/3, and the y-intercept is -2.

To graph the line, plot a point at (0,-2). This is the point where the graph crosses the y axis. Then from that point, count up two and right 3. Plot a point here as well. Lastly, connect the two points with a straight line.

See attached picture for the graph.
