yulyashka [42]

This is therefore a positive slope, which belongs to a line that rises 1/10 units every one unit run.

What is the slope of a line example?

Whenever the equation of a line is written in the form y = mx + b, it is called the slope-intercept form of the equation. The m is the slope of the line. And b is the b in the point that is the y-intercept (0, b). For example, for the equation y = 3x – 7, the slope is 3, and the y-intercept is (0, −7).

Use the formula to find the slope of a segment through two points (x1 , y1) and (x2,y2) on the plane:

slope= ( y2-y1)/(x2-x1)

we can name (x1,y1)  = (-4 , 2)

and (x2,y2)  = (6 ,3)

Therefore, the slope becomes: ( y2-y1)/(x2-x1)=( 3-2)/(6+4)= 1/10

This is therefore a positive slope, which belongs to a line that rises 1/10 units every one unit run.

What is the first step to show that two lines are parallel, by looking at the equations of the lines, if they are written in sta
kotykmax [81]
<span>You do need the slope. It's not obvious in "Standard Form". Ax + By = C ==> y = -(A/B)x + (C/B) There's your slope to compare. Find -A/B for each. 3x + 2y = 4 ==> Slope = -3/2 6x + 4y = 5 ==> Slope = -6/4 = -3/2 3x + y = 4 ==> Slope = -3 The top two examples COULD be parallel. If the constant is the same, that's a bit sneaky because they are really the SAME line. That's not really parallel.</span>
