First let's find the slope
Slope formula:
![\frac{y_2-y_1}{x_2-x_1} =slope](https://tex.z-dn.net/?f=%20%5Cfrac%7By_2-y_1%7D%7Bx_2-x_1%7D%20%3Dslope)
Given the two coordinates:
(-4,-7) (3,2)
x1,y1 x2,y2
Plug these numbers into the formula
![\frac{2-(-7)}{3-(-4)} = \frac{9}{7}](https://tex.z-dn.net/?f=%20%5Cfrac%7B2-%28-7%29%7D%7B3-%28-4%29%7D%20%3D%20%5Cfrac%7B9%7D%7B7%7D%20)
In this case the mistake that was made was that the student wrote the slope negative instead of positive

Answer:
1) = 90=acute angle 2)103=acute angle
Step-by-step explanation:
Answer:
Step-by-step explanation:
Remark
The last digit is 1 3 5 7 9 because the last digit is odd.
The first digit must be a 3 because the number is between 300 and 350
Let the first digit = x
Let the second digit = y
Let the third digit = z
x + y = z
x + y + z = 14 Substitute z for x + y
z + z = 14 Combine
2z = 14 Divide by 2
2z/2 = 14/2
z = 7
The first digit is 3 and the third digit = 7
The middle digit is 3 less than the last digit.
y = 7 - 3 = 4
Answer
347
First plug in the numbers 5 x 8 = 40
40-4y+6x8=48
40-4y+48
I think that the value of n is -10
