The definition of "slope" is the element via which a line will enhance or decreases. In linear equations, like y=6/5x+5, the coefficient of x is often going to be the slope. The "y intercept" refers back to the quantity at which the line intersects with the y axis. The quantity this is extra or subtracted to this is going to consistently be the y intercept. it is extra effectual illustrated with the time-honored type for a linear equation, this is: y = mx + b the place m = slope and b = the y intercept. so which you would be able to graph all of this, you graph (0.5), this is the y intercept, then as you pass one million to the ideal, you pass up 6/5, considering this is the slope. and additionally you preserve doing that for numerous factors till the graph is sufficient to your instructor. i desire this enables!

You need to know more information. Do you know a point on the graph? If so, you can use point-slope form.
(y-y1)=m(x-x1), where y1 and x1 are the coordinates of the known point and m is the slope. Plug those into the equation, solve for y, and the coefficient at the end will be your y-intercept.

General equation for a line is:
y = mx + b
where m = slope and b = y-intercept
Let's change this around to make it useful to you:
y = mx + b
y - mx = mx + b - mx (subtracted mx from both sides)
y - mx = b
Since you know the slope (m), just select any point on the line (x,y) and substitute it into the new equation above to find b (y-intercept).

its the y intercept of a line. You will need a slope aand a point or 2 pairs of points

Assuming you possess enough information to define the line you may solve for the y-intercept by first defining the line in terms of y and then setting x equal to zero in most cases.

use da point-slope formula: y – y1 = m(x – x1)
