2-6/3-5

-4/-2

Slope = 2

Plug into the equation with either (5,6) or (3,2)

6 = 2(5) + b

6 = 10 + b

b = -4

y = 2x - 4

Answer:

the slope is 2, so 2x+b=y

substitute the values into the equation

6+b=2

the y-intercept (b) is -4

y=2x-4

Solve y=3x-7 and 4x+3y=18 by substitution

sveta [45]

Answer:

x = 3 and y = 2

Step-by-step explanation:

y = 3x - 7

substituting for y in 4x + 3y = 18, we will have

4x + 3(3x -7) = 18

4x + 9x - 21 = 18

13x = 18 + 21

13x = 39

x = 3

Substituting for x in y = 3x -7, we have

y = 3(3) - 7

y = 9 - 7

y = 2

Lesechka [4]

Answer:

-12 + 2i

Step-by-step explanation:

$\sqrt{ - 4} - \sqrt{144} \\ \\ = \sqrt{ - 1 \times 4} - \sqrt{144} \\ \\ = \sqrt{ - 1} \times \sqrt{4} - \sqrt{144} \\ \\ = i \times 2 - 12 \\ \\ = - 12 + 2i \\ \implies \: a + bi$
