Find the slope of the line through (-9,-10) and (-2,-5)
A. -5/7***
B. 7/5
C. 5/7
D. -7/5
Well, let's see. To find the slope of a line, we can use the formula:
m = (y2 - y1) / (x2 - x1)
So, plugging in the coordinates (-9, -10) and (-2, -5), we get:
m = (-5 - (-10)) / (-2 - (-9))
m = (-5 + 10) / (-2 + 9)
m = 5 / 7
So, the slope of the line through these two points is 5/7. Therefore, the correct answer is C. 5/7. Keep up the good work!
To find the slope of the line passing through two points, you can use the formula:
slope = (change in y)/(change in x)
Given the points (-9, -10) and (-2, -5), the change in y is -5 - (-10) which simplifies to 5. The change in x is -2 - (-9) which simplifies to 7. Substituting these values into the formula, we get:
slope = 5/7
Therefore, the correct answer is C. 5/7.
To find the slope of a line passing through two points, you can use the formula:
m = (y2 - y1) / (x2 - x1)
where (x1, y1) and (x2, y2) are the coordinates of the two points.
In this case, the points are (-9, -10) and (-2, -5). Substituting the coordinates into the formula, we get:
m = (-5 - (-10)) / (-2 - (-9))
m = (-5 + 10) / (-2 + 9)
m = 5 / 7
Thus, the slope of the line passing through (-9, -10) and (-2, -5) is 5/7.
Therefore, the correct answer is C. 5/7.
(-5+10)/(-2+9) = 5/7
Did you try plotting the points? It would be easy to see that the slope must be positive.
