How would you explain slope?

Slope is the "steepness" of a line. If the line is on a grid, it can be calculated by dividing rise/run. If the line is given in the form of the equation y = mx + b the slope is the value of m.


What is an equation of the line that passes through the point 50 and is perpendicular to the line 5x 6y24 express your answer in slope-intercept form?

Here is how to solve it. First, find the slope of the given line. To do this, solve the equation for "y". That will convert the equation to the slope-intercept form. From there, you can immediately read off the slope. Since parallel lines have the same slope, the line you are looking for will have the same slope. Now you need to use the point-slope form of the equation, with the given point, and the slope you just calculated. Finally, solve this equation for "y" to bring it into the requested slope-intercept form.


What is the slope of the line given by the equation y3.8x?

The equation provided does not have a defined slope. The slope of a line is determined by the coefficient of the x-term in the equation, but there is none in the given equation.


How do write an equation of a line when given the slope a point of the line?

if a line has a slope of -2 and a point on the line has coordinates of (3, -5) write an equation for the line in point slope form


Writing an equation given a slope and a point?

If the slope m is given at a point (xo, yo) of a line, then the equation of the line is given by: y - yo = m(x - xo)


What is the slope of a line when you are given the equation 3y equals -3x - 5?

The slope of the graph of that equation is -1.


What is the slope of the line given by the equation below?

There is no equation there but the slope of the line is the number that multiplies x in the straight line equation y = mx + b whereas m is the slope and b is the y intercept


What is the slope of the line given by the equation y equals 3x?

Slope = 3


What is an equation in slope-intercept form for the line that passes through the given point and is parallel to the given line?

Write an equation in slope-intercept form for the line that passes through the given point and is parallel to the given line (-7,3); x=4


Which equation represents a line perpendicular to the graph of 3x-6y12?

Solve the line equation for "y", to get it in slope-intercept form. You can immediately read the slope from this equation.Divide -1 by (slope of this first line) to get the slope of the second line - the one perpendicular to the given line. Write an equation for any line with this slope.


What is an equation in point-slope form of the line having the given slope that contains the given point.?

The straight line equation is: y = mx+c whereas m is the slope and c is the y intercept


What is the slope of the line given by the equation y -3x?

If you mean: y = -3x then the slope of the line is -3
