What is the equation of this line?
elena-14-01-66 [18.8K]

Answer:

A) y = 4/3 x - 1/3

Step-by-step explanation:

(4,5) and (-2,-3)

Slope = (5 + 3)/(4 + 2)

= 8/6

= 4/3

Equation

y + 3 = 4/3(x + 2)

y + 3 = 4/3 x + 8/3

y = 4/3 x + 8/3 - 9/3

y = 4/3 x - 1/3

Answer:

y = 4/3 x - 1/3

Help me pls math genius
Alecsey [184]

Answer:

x = -3

y = -1

Step-by-step explanation:

in the given question :-

=》x - 4y = 1

=》x = 4y + 1

now replacing the value of x as ( 4y + 1 ) in equation (2)

=》3x + 2y = -11

=》3 (4y + 1) + 2y = -11

=》12y + 3 + 2y = -11

=》14y = -11 - 3

=》y = -14 ÷ 14

=》y = -1

now, putting the value of y in equation (1)

=》x - 4y = 1

=》x - ( 4 × -1 ) = 1

=》x + 4 = 1

=》x = 1 - 4

=》x = -3
