(01.05) What is the equation of a horizontal line passing through the point (-3, 8)?
A: x=-3
B: y=8
C: x=5
D: y=-11

B

Step-by-step explanation:

The equation of a horizontal line is

y = c

where c is the value of the y- coordinates the line passes through.

The line passes through (- 3, 8 ) with y- coordinate of  8, thus

y = 8 ← equation of horizontal line

answer: i think it's a

step-by-step explanation:

arrange the equations with like terms in columns.

analyze the coefficients of x or y.

add the equations and solve for the remaining variable.

substitute the value into either equation and solve.

check the solution.
