How do I write an equation in slope-intercept form for a line perpendicular to the graph of the equation that passes through the x-intercept of that line?
As for example the perpendicular equation to line y = 2x+6 could be y = -1/2x+6 because the negative reciprocal of 2x is -1/2x
What is the y intercept in an equation?
It is part of the equation that intercepts the y axis For example the straight line equation: y = 2x+4 is in slope-intercept form and 4 is the y intercept and 2 is the slope.
What is an example of a linear equation?
The slope-intercept form of a linear equation is y = mx + b where m = slope and b = the y-intercept.
What value represents the Y intercept?
For example in the straight line equation of y = 3x+9 the y intercept is 9 and the slope is 3
A negative plus a negative is positive?
No a negative plus a negative is not a positive answer. example. -5+-2=-7 but if you are subtracting a negative number from a negative, then the second negative number would become a positive. example. -5 - -2= -5+2= =-3
How do you know when the slope of a line is negative?
You know when the slope of a line is negative when m in the slope-intercept form equation y=mx+b is negative. For example, y=-3x+2 has a negative slope since m (which is -3 in this case) is negative. This is the same when finding a positive slope, because if m is positive, then the slope is positive.

How can you write an equation of A line when you are given the slope and the y-intercept of the line?
As for example if the slope is 3 and the y intercept is 6 then the equation is: y=3x+6
Where is the y-intercept of any direct variation equation?
As for example in the straight line equation: y = 3x+5 the y intercept is 5 and the slope or gradient is 3
What two things are needed to be able to write an equation in slope-intercept form?
The slope of x and the y intercept as for example in the straight line equation of y = 2x+3 the slope is 2 and the y intercept is 3
What a negative divided by a positive?
A negative divided by a positive is negative. An example is -2/6= -3
How can you use slope intercept form to write an equation of a line givven its slope and y intercept?
y intercept is b and slope is m Equation is y = mx + b For example if y intercept (where x = 0) is -3 and slope is 4 then y = 4x-3
Is the sum of a positive number and negative number always a negative number?
No. In the case of 5 + (-3), for example, the positive number 2 is the solution. The sum would only be negative if the absolute value of the negative number is greater than the positive number.
If you divide a positive number by a negative number is the answer positive or negative?
Negative. Example: 3/-3= -1
What value represents the Y intercept?
For example in the straight line equation of y = 3x+9 the y intercept is 9 and the slope is 3
