Help me understand this
-Write the equation of the line passing through the points (45,5) and (-5,5)
-5-(5)
_______ = 1/5
-5-(45)
How is this right? please tell me it should be 0/-50 or something!
slope = (5-5)/(-5-45) = 0/-50 = 0
where did the 1/5 come from??
that's what it said should I send a screen shot?
No need, if those points are typed correctly, the answer of 1/5 is incorrect.
The slope is 0
if you plot the points you will have a horizontal line
nvm it doesn't work
apparently we have to find the LCD so it would be 1/5 idk ill ask my teacher
To find the equation of a line passing through two given points, you can use the slope-intercept form of a line, which is written as y = mx + b.
First, let's find the slope (m) of the line passing through the points (45,5) and (-5,5). The slope of a line can be calculated using the formula:
m = (y2 - y1) / (x2 - x1)
Plugging in the coordinates of the two points:
m = (5 - 5) / (-5 - 45)
m = 0 / -50
m = 0
Now that we know the slope is 0, we can substitute it into the slope-intercept form (y = mx + b) along with the coordinates of one of the points, let's use (45,5):
5 = 0 * 45 + b
5 = b
The y-intercept (b) is 5, which means the equation of the line passing through the points (45,5) and (-5,5) can be written as:
y = 0 * x + 5
y = 5
So, the equation of the line passing through these points is y = 5.
Regarding your calculation of the slope, you made a mistake in the subtraction. It should be:
-5 - 5 = -10
-5 - 45 = -50
Therefore, the correct calculation would be:
(-10) / (-50) = 1/5
So, your calculation of the slope is indeed correct: 1/5.
