Every straight line can be represented by an equation: y = mx + b. The coordinates of every point on the line will solve the equation if you substitute them in the equation for x and y.
The slope m of this line - its steepness, or slant - can be calculated like this:
m = change in y-value
change in x-value
The equation of any straight line, called a linear equation, can be written as: y = mx + b, where m is the slope of the line and b is the y-intercept.
The y-intercept of this line is the value of y at the point where the line crosses the y axis.

How do you find the x and y-intercepts without using a graph?
-- Take the equation. -- Say to yourself, "At the x-intercept, y=0". Set 'y' equal to zero, solve the equation for 'x', and you have the x-intercept. -- Take the original equation again. -- Say to yourself, "At the y-intercept, x=0". Set 'x' equal to zero, solve the equation for 'y', and you have the y-intercept.
How do you find slope and y-intercept of a line?
By using the straight line equation of y = mx+c whereas m is the slope and c is the y intercept
What would the equation in slope-intercept form of the line that has a slope of -7 and y-intercept 6?
If the y intercept is -6 then the equation is: y = -7x-6
What is the slope and y-intercept and x-intercept of y equals -7?
Slope is zero y-intercept is -7 there is no x-intercept for this equation
How the you Write the equation in slope-intercept form of the line that has a slope of 2 and y-intercept of -2?
slope-intercept from is y=mx+b, m is the slope and b is the y-intercept. put the values of the slope and y-intercept into the equation. y=2x-2
