Question

Find the missing coefficient in the equation of the line that passes through the given point.

5.) Ax + y = 3;(2,-5)

6.) 3x + By= -1;(2, 7)

Help!! Please

Answer 1

5) A = 4

6) B = -1

Explanation:

Question 5

Substitute (2, -5) into the equation to find the missing coefficient

A(2) + (-5) = 3

2A - 5 = 3

2A = 8

A = 4

Question 6

Substitute (2, 7) into the equation to find the missing coefficient

3(2) + B(7) = -1

6 + 7B = -1

7B = -7

B = -1
