4.2 writing equations in slope intercept formLyndeeGovert
?
The document discusses writing linear equations in slope-intercept form. It reviews that the slope-intercept form is y=mx+b, where m is the slope and b is the y-intercept. It provides examples of writing equations given the slope and y-intercept, given a point and the slope, and finding the equation of a line passing through two given points by first calculating the slope and then using one of the points to find the y-intercept.

Equivalent fractions are fractions that have the same value but look different because they have different numerators and different denominators. Effective strategies that I have used in the classroom are shared in this video #equivalentfractions
The document discusses the derivation of the logarithmic derivative of several functions:
1) For the function y = xln(x), the logarithmic derivative is y'/y = 1/x.
2) For the function y = 2^3x, the logarithmic derivative is y'/y = 3/2x.
3) For the function y = x(x^2-1)/(x^2+1)^(1/2), the logarithmic derivative is y'/y = (3x^2-1)/(x^3-x) - 4x/(x^2+1).
The document contains definitions of several sets and relations. It defines sets of numbers like A = {1, 2, 3, 4, 5} and relations between elements of sets like R = {(x, y) ¡Ê A ¡Á A / y is a multiple of x}.

Dr. Ansari Khurshid Ahmed- Factors affecting Validity of a Test.pptxKhurshid Ahmed Ansari
?
Validity is an important characteristic of a test. A test having low validity is of little use. Validity is the accuracy with which a test measures whatever it is supposed to measure. Validity can be low, moderate or high. There are many factors which affect the validity of a test. If these factors are controlled, then the validity of the test can be maintained to a high level. In the power point presentation, factors affecting validity are discussed with the help of concrete examples.
