Slope intercept form from a graph

How do you find the y-intercept from a graph?

• By locating the point where the line crosses the y-axis.

• By finding the slope of the line.

• By determining the x-intercept of the line.

• By calculating the area under the curve.

What does a slope of 0 indicate about a line?

• The line is vertical and rises steeply.

• The line is horizontal and does not rise or fall.

• The line has a positive slope and rises to the right.

• The line has a negative slope and falls to the right.

If a line has a slope of 3, what does this mean?

• A slope of 3 means that for every 1 unit increase in x, y increases by 3 units.

• A slope of 3 means that for every 3 units increase in x, y increases by 1 unit.

• A slope of 3 means that the line is vertical.

• A slope of 3 means that the line is horizontal.
