Line A passes through the points (-5, 1) and (5, 11).
11111nata11111 [884]
Line A:m = \frac{y_{2} - y_{1}}{x_{2} - x_{1}} = \frac{11 - 1}{5 - (-5)} = \frac{10}{5 + 5} = \frac{10}{10} = 1
y - y₁ = m(x - x₁)
 y - 1 = 1(x - (-5))
 y - 1 = 1(x + 5)
 y - 1 = 1(x) + 1(5)
 y - 1 = x + 5
   + 1       + 1
       y = x + 6

Line B:m = \frac{y_{2} - y_{1}}{x_{2} - x_{1}} = \frac{20 - (-1)}{-3 - 4} = \frac{20 + 1}{-7} = \frac{21}{-7} = -3
   y - y₁ = m(x - x₁)
y - (-1) = -3(x - 4)
   y + 1 = -3(x) + 3(4)
   y + 1 = -3x + 12
       - 1          -    1
         y = -3x + 11

y = x + 6
y = -3x + 11

     x + 6 = -3x + 11
+ 3x        + 3x
   4x + 6 = 11
         - 6   - 6
         4x = 5
          4     4
           x = 1¹/₄
           y = x + 6
           y = 1¹/₄ + 6
           y = 7¹/₄
     (x, y) = (1¹/₄, 7¹/₄)

The answer is B.

german
27 in the first group, 36 in the second. Here's the work: Divide 63 by 7 (3 parts plus 4 parts) equals 9. Multiply 9 by 3 for the first group and you get 27, multiply 9 by 4 for the second group to get 36.

If 5 cars each costing $34,000 were sold you would add those together which equal 170,000 and then find 5% of 170,000 which is 8500 so if the car sales man earns 5% he got $8500 this month
