math class that i have take : geometry, algebra1 my first class of math was pretty bad becouse i was a new boy in this country so i wasnt ready for this class of math my algebra class was good i liked it and i learned alot of thing the best way the teacher use to help us to understand was doing a good projects and sometimes she did different kind of games 1.2 1. in line two we put the 10 out side of the keys to multiply all the equation by 10 2.line 2 and 3 are the result of the fraction multiplied by 10 3. line 3 and 4 is using X to solve the equation 4.line 4 and 5 commune subtraction occurs 5. line 5 we divide 60/1 line 6 is the result of the division 6.in line 7 we use the original equation and plug in the x that we got before 7.line 7 and 8 we got the result of the multiplication with the value of x in the equation. 8.line 9 we add and subtract the number to get the answer

 * Linear Function:A mathematical [|equation] in which no independent-variable is raised to a [|power] greater than one. A simple linear function with only one [|independent variable] (y = a + bx) traces a straight line when plotted on a [|graph]
 * Relation: a generalization of arithmetic relations, such as "=" and "<", that occur in statements, such as "5 < 6" and "2 + 2 = 4"
 * Domain:Set of all (permissible) x values To find the Domain, solve for y in terms of x.
 * Range:Set of all (resulting) y values To find the Range, solve for x in terms of y.
 * Increasing:The graph of an increasing function always goes up from left to right. A function is increasing at all the points where its derivative is positive
 * Decreasing:We all know that if something is increasing then it is going up and if it is decreasing it is going down. Another way of saying that a graph is going up is that its slope is positive. If the graph is going down, then the slope will be negative. Since slope and derivative are synonymous, we can relate increasing and decreasing with the derivative of a function. First a formal definition.
 * Slope: describes its steepness, incline, or grade. A higher slope value indicates a steeper incline.The slope is (in the simplest of terms) the measurement of a line, and is defined as the ratio of the "rise" divided by the "run" between two points on a line, or in other words, the ratio of the altitude change to the horizontal distance between any two points on the line. Given two points (//x//1,//y//1) and (//x//2,//y//2) on a line, the slope //m// of the line is m=x/y=rise/run
 * Intercept:is a point where the graph of a function or relation intersects with the //y//-axis
 * Degree: is a measurement of plane angle, representing 1⁄360 of a full rotation; one degree is equivalent to π/180 radians. It is not an SI unit, as the SI unit for angles is radian, but it is mentioned in the SI brochure as an accepted unit.[1home] When that angle is with respect to a reference meridian, it indicates a location along a great circle of a sphere, such as Earth (see Geographic coordinate system), Mars, or the celestial sphere.[2home]
