To find the y-intercept from a graph - look at where the graph of the line intersects the y-axis. The point at where the graph of the line crosses the y-axis will be the y-intercept with the coordinates of (0,y) The point at which the line cuts the y – axis is called as y – intercept.
You can locate the point by seeing the graph.
Note:
If you are given a linear equation say ax + by + c = 0
Now if we plug x = 0 in the given equation we will get the y – intercept.
y = -c/b
If the given equation is of the form y = mx + b
b is the y – intercept of the line. Source: www.icoachmath.com

How do you find the coordinates of y-intercept and x-intercept on a graph?
You can either measure or estimate the coordinates visually from the graph, or solve the equation underlying the graph.
Find the slope and the y-intercept what linear equation. Then graph 2x plus y equals -3?
2x plus y = -3 (subtract 2x from both sides) y = -2x - 3 slope = -2 y-intercept = -3
How do you find that the graph K34 has how many edges?

How can you find coordinates on a line graph?
Select any value for one of the variables in the graph and solve the equation to get the other variable.
How do you find the vertex and graph?
y = - x2 +6x - 5.5
