Answer:
x + 3y = 21
Step-by-step explanation:
Equation of the line: y =mx+ b
Multiply the equation by 3
3y = -x + 21
x + 3y = 21

Answer:
Step-by-step explanation:
Slope intercept form: y = mx + b
Find slope:
m = (y₂ - y₁) / (x₂ - x₁)
= (-5 - (-4)) / (0 - 4)
= -1 / -4
= 1/4
Find y intercept using anyone of the given points and slope from above:
y = mx + b
b = -5
Now use the above slope and y intercept to create equation of a line:
