How do you find the x-intercept and the y-intercept of a graph?
X axis is across and Y axis is down
How do you find a y-intercept of a scatter plot?
You have to put a line of best fit onto the graph and find where that line crosses the y-axis.
How do you graph a line if given the equation in slope-intercept form?
Slope intercept form is y = mx + b, where m is the slope and b is the y intercept. To graph this, look at b. The number there is the y intercept. Look on the y axis on the graph and find the place where that number occurs. Plot that point, which will be (0, b). Then look at the m term. This is the slope. Imagine this number as a fraction. If it is a whole number, imagine it as the whole number divided by one. The fraction is the slope. The numerator is how far you move up or down, and the denomontator is how far you move left and right on the graph. Find the second point this way, then you can draw your line. Hope this helps!
How can you go between tables and graphs and equations?
from a table to a graph just graph x and y (on a coordinate plane) from table to equation find the slope of the line and the y intercept. your equation should be in the form y=mx+b where m is the slope and b is the y intercept
Which graph represents the equation x equals 4?
Every point on the line x=4 will have to have an x value of 4. When plotting a graph of x=4, you will find that it turns out to be a vertical line, parallel to the y axis. This is because you can choose whatever y coordinate you want, but as long as the x coordinate is 4, it will be on the line x=4. The x intercept will, therefore, be 4. There is no y intercept as it never crosses the y axis.
