Answer:
<em>y=-6</em>
Step-by-step explanation:
<u>Proportions</u>
A direct proportion is a relation between variables where their ratio is a constant value. This means that if y and x are proportional, then:
y = kx
Where k is the constant of proportionality.
Substituting x=-3 y=9:
9 = k(-3)
Now the relationship is:
y = -3x
For x=2
y = -3(2) = -6
Answer:
2x +3y = -10
Step-by-step explanation:
The given line equation is in standard form, so the one we write will match that form. A parallel line will have the same x- and y-coefficients, but a different constant on the right.
Put the point values in the left-side expression to find the required right-side constant: (x, y) = (1, -4)
2(1) +3(-4) = constant = 2-12 = -10
Your line is ...
2x +3y = -10
