week 15 in math 10

this week in math 10 we learned equations of lines. I am going to show you how to change point slope form into slope y intercept form.

the first step is to distribute the number from infront of the bracket into the numbers inside. then you want to flip the number beside the y to the other side (when you do this you must change the sign) then if possible add the two constants and then you are done.

week 14 in math 10

this week in math 10 we learned how to find the slope using a graph or cooridates. there are four types of slopes there is a posative slope, negative slope, zero slope and an undefined slope. a posative slope starts on thebottom on the left and goes up with a slpoe right, a negative slope is the opposite it starts on the bottom right and goes up left, a zero slope is a straight horizontal line, and the undefined slope is a straight verticle line.

to find the slope you use the formula slope=rise/run, the rise is the y axes and run is the x axes. you then need to find two perfect points, this is a point on a grid line. after you get your two perfect points you start on the left with the rise (y axes) and go up or down depending on if its a posative or negative slope, then you find how many points it goes down or up to get to the next point and you find how many points it goes left or right to get to your next point. then you write a fraction of the two numbers (rise over run) and divide them too get your slope.

week 13 in math 10

this week in math 10 we learned how to find the x and y intercepts. to find the x intercept the first step is you have to cancil out the y in the equation. to do this you have to replace the y with a zero(5x-4y-18=0)to(5x-4(0)-18=0). the next step is to isolate the variable, to do this you need to get rid of the term with no x or y by adding or subtracting by that number, and what you do to the left you do to the right. then you need to divide by the the number the with the x, so if it is 3x=18 you divide both  terms by three to isolate the variable but if you x is squared you have to square root the x and the answer you have, then you have your answer

to find the y axes everything is the same except you need to change the x with 0
