we use the formula y = mx + b where m is the slope and its the number multiplied by x, any other number is the y-intercept

How do you identify the y-intercept and slope in an equation of a line?

Masssage the equation around until you have it in the form: Y = Ax + B, 'A' and 'B' are numbers. Once you have it in that form, 'A' is the slope of the line, and 'B' is the y-intercept.


How you can identify the y-intercept of the line y 7x 4 without graphing it?

When y = 7x +4 the y intercept is 4 and the slope is 7


How do you write an equation of parallel lines in slope-intercept form?

To write an equation of parallel lines in slope-intercept form (y = mx + b), first identify the slope (m) of the line you want to be parallel to, as parallel lines have the same slope. Then, choose a y-intercept (b) for the new line—this can be any value. Substitute the slope and the chosen y-intercept into the slope-intercept form to get the equation of the parallel line. For example, if the original line is y = 2x + 3, a parallel line could be y = 2x + 1.


What is the formula for slope intercept form a line?

The slope intercept equation of a line is y=mx+b, where m is the slope of the line and b is the y-intercept.


What is the slope and-y intercept?

In the equation y = mx + b the slope is m and the y-intercept is b. The slope of the line is how "steep" the line is, and the y-intercept is where it crosses the y axis.


What is the slope of the line given by the equation below y 12x - 23?

To find the slope of the line given by the equation ( y = 12x - 23 ), we can identify the slope from the standard slope-intercept form ( y = mx + b ), where ( m ) is the slope and ( b ) is the y-intercept. In this equation, the slope ( m ) is 12. Therefore, the slope of the line is 12.


What is the slope of a line that has a y-intercept but no x-intercept?

A line with a y-intercept but no x-intercept will be a straight line parallel to the x axis. It will have a slope of zero.


What are the slope and y-intercept of a horizantal line?

Slope=0 Y-intercept=0


What is the equation of a line with slope of -3 and a y-intercept of 4?

The equation of a line can be expressed in the slope-intercept form, which is ( y = mx + b ), where ( m ) is the slope and ( b ) is the y-intercept. Given a slope of -3 and a y-intercept of 4, the equation of the line is ( y = -3x + 4 ).


What is the intercept in a slope intercept form?

An intercept is where the graph crosses an axis.A line in slope-intercept form is in the form y = ax + b, where "a" is the slope, and "b" is the y-intercept. For example, if y = 3x -4, the slope of the line is 3, and it crosses the y-axis at -4.


What are the slope and y-intercept of a horizontal line?

Slope = zero Y-intercept can be any number.


Graphing linear equation using the slope and y-intercept of the line?

The y-intercept, together with the slope of the line, can also be used in graphing linear equations. The slope and y-intercept of a line can be obtained easily by inspection if the equeation of the line is of the form y=mx+b where m is the slope and b is the y-intercept.
