Texas Instruments TI-84 Plus Calculator "finding slope line" Questions

...line that has the slope can be graphed if you have its complete equation y=slope*x + initial value. To graph a curve on the TI84 open the Y= editor, type in the second member (right side) of the ...

slope. If the line is going up to the right. the slope is positive. If it is going up to the left, the slope is negative.

"describe what it means in terms of the rate of change of the dependent

Find a slope intercept equation for the line with the indicated slope and y intercept Slope 4/5 y intercept (0-9) The equation is? http://www.webmath.com/equline3.html

...line, the slope will be the negative reciprocal. For example, y = 3x + 5, the line perpendicular would be y = - 1/3 x + b. Another way of looking at this is if you take the slopes of the two line and ...

...slope of the original line is 1/4, so the multiplying it -1, we get -1/4, and taking the reciprocal, we get -4. So the slope of the perpendicular line is -4.

So, y = -4x + b, but we don't know ...

...slope of -5, so it is parallel to y=-5x + 1 Is the point (-4,-6) on the line? Let's substitute it in to see if it is on the line. Again, everywhere we see an x, we put in -4 and everywhere we see a y ...

slope of a line difference in y (Y2-Y1) divided by difference in x (X2-X1). Example: 1st point (5,3) and second point (10,6) means subtract 3 from 6 (2nd y value from first)= 3- this is your numerator

...you find a straight line that has a positive slope and itersects the y axis at y=2. To graph it [Diamond][Y=] on line Y1= enter X+2 [ENTER]. Then [Diamond][GRAPH] . Here is what you see. Hope it ...

...11.8 Find gradient(m),intercept(c)and the relationship Use the statistics feature called linear regression to find the slope (m) and the intercept (b) then write the equation of the best line as ...

...slope (-1/3).So the equation of your line starts this way: y=(-1/3)x+b.To identify (calculate) b, you must make use of the fact that the parallel line passes through the point (1,5). That means that ...
