Answer:
The answer is x + 4y = 7
Equation of a line is y = mx + c
Where m is the slope
c is the y intercept
Slope of the line between the points
(-1, 2) and (3, 1) is
Slope = 1-2/ 3+1 = - 1/4
Equation of the line using point
(-1, 2) is
y - 2 = -1/4(x + 1)
4y - 8 = - x - 1
x + 4y = 7
Hope this helps you
The answer to number one is C

Answer:
The number is 31
Step-by-step explanation:
Let the number be x
Subtract 12 from the number = x - 12
Then multiply the difference by -7 = (-7)*(x - 12)
(-7)(x - 12) = -133
-7x - 12*(-7) = -133
-7x + 84 = - 133
-7x = -133 - 84
-7x = -217
x = -217/-7
x = 31
