Introduction to nine-grade math slope:
Nine- grade math slope article deals with how to find the slope from the slope intercept from of the equation and from the two given points of the line. It includes the slope of the parallel and perpendicular line. We have the different formula to find the slope of the given line
Is this topic How to Construct a Perpendicular Bisector hard for you? Watch out for my coming posts.
Formula related to nine grade math slope.
When two coordinate points on the line is given
Formula to find slope, m = `((y2-y1)/(x2-x1))`
When slope intercept form is given
The slope intercept form is y = mx+b
m = `((y-b)/x)`
Where m is the slope of the line
b is the y intercept.
When two lines are parallel to each other, the slope of the both lines is equal.
When two lines are perpendicular to each other, the product of slope is -1[ (m1*m2)= -1]
I have recently faced lot of problem while learning fun math problems for kids, But thank to online resources of math which helped me to learn myself easily on net.
Model problems for nine grade math slope
Example problems for nine grade math
Find the slope of the line whose coordinate points are (2, 3) and (4, 5).
Solution:
(x1,y1) = (2, 3)
(x2,y2) = (4, 5)
Formula:
Formula to find slope, m = `((y2-y1)/(x2-x1))`
= `((5-3)/ (4-2))`
= `(2/2)`
= 1
The slope of the line is 1
2.find the slope of the line whose slope intercept form is 3y = 6x +9
Solution:
The slope intercept form is y= mx+b
The given equation is 3y= 6x +9
rewrite the equation of the line
y= `(6/3)x+(9/3)`
y= 2x+3
Now it is in the standard form.
Therefore, the slope of the line is 2
3. Line AB and CD are perpendicular to each other, find the slope of the line CD when the two points on the lineAB is (2, 7) and (6, 4)
Solution:
(x1,y1) = (2, 7)
(x2,y2) = (6, 4)
Formula:
Formula to find slope, m = `((y2-y1)/(x2-x1))`
= `((4-7)/(6-2))`
= `((-3)/4)`
= `(-3/4)`
The slope of the line is `(-3/4)`
Since AB and CD are perpendicular to each other.
so, the slope of the CD =` (- 1/"slope of AB")`
= `(-1/ ((-3/4)))`
= `(4/3)`
Slope of the line CD is `(4/3)`

so, the slope of the CD =` (- 1/"slope of AB")`
= `(-1/ ((-3/4)))`
= `(4/3)`
Slope of the line CD is `(4/3)`
