this problem is in slope form so u would solve it by adding 3 to both sides (to isolate your "y" value. in this equation your slope would be 2 because slope formula is y= mx+b M is your slope

slope = m = (Y2-Y1)/(X2-X1) = (-4-8)/(8-8) Oh my, we have a problem, the slope is undefined because of zero denominator. The line with infinite slope goes straight up, constant x so the solution is x = 8

College math
Both of your equations are straight lines. So they have the same slope no matter where you are on the line 21. y = -4x + 5 compare with y = mx + b, where m is the slope slope = -4 let me know what you got for 22.

algebra, equations
y=mx+b slope is m y intercept is b so in this problem the slope is -2/3 the y intercept is -12

algebra
the slope of the first is -2/5 and the slope of the second is 5/2 notice their product is -1, so they are perpendicular. (slopes are negative reciprocals of each other) (to get the slope in my head I used the rule: for Ax + By = C, slope = -A/B )

Math-Algebra
For any equation in the form Ax + By = C the slope is -A/B so the slope is ..... ? The slopes of perpendicular lines are negative reciprocals of each other. e.g. if the slope of some line is 4/11, then the slope of the perpendicular line is -11/4 let me know what you got.

calculus
Just check the slope on each interval. increasing when slope > 0 constant when slope = 0 decreasing when slope < 0 Looks like it's constant at 2 for x in (-7,-1) After that, it's increasing with slope = 1/2

I do not know what you want about y = m x + b However I do understand below 8) Through (4,0) and slope of -1 y = - x + b 0 = -4 + b b = 4 so y = -x + 4 0) through (4,5) with slope -8 y = -8 x + b 5 = -8*4 + b 5 = -32 + b b = 37 so y = -8 x + 37 10) through (-2,4) with slope 7 ...

Math(Algebra)
slope of first is 2/3 second is y = -3 x/2 + 1/2 slope = m' = -3/2 the slope of the second is negative the inverse of the slope of the first, so they are perpendicular m' = -1/m

Unless you know the slope, you can not. What is the rest of the problem?

algebra please check :(
The slope of an equation y=mx+c is equal to m. Therefore the slope of y = -x -5 is -1, and the slope of y = x +5 is +1. Two parallel lines MUST have the same slope, and vice versa. So what is your conclusion, and why?

Math
The equation of a straight line is usually written in Slope-Intercept Form : y = mx + b Rewrite second and third equations: -3 x + y = 5 y = 3 x + 5 ( Slope = 3 ) 2 y = -6 x + 12 Divide both sides with 2 y = -3 x + 6 ( Slope = - 3 ) Parallel lines have the same slope. Lines: y...

Ooh, ok! The form of this linear equation is called slope-intercept form, because you can easily find the slope and y-intercept just by looking at it. Slope-intercept form: y=mx+b m stands for the slope, and b stands for the y-intercept (when x=0) So, your slope is the number ...

To come up with numerical answers, numerical data must be provided. We are physicists, not psychics. You should have been provided with the slope of the incline and the speed at the bottom. Anyway, here is how to do this problem yourself. Use conservation of energy to deduce ...

Find the slope of the line through the given points. ( 8, -2) and ( 8, -1) Since 8-8 is 0 would the slope be 0 or would there be no slope?
