Answer:
Step-by-step explanation:
y=kx
4=k(-2)
k=-2
y=-2x
when x=30
y=-2*30=-60
Answer:
Option D
Step-by-step explanation:
' y = 4x − 1' would graph as a straight line. Therefore, it is a linear equation.
Liner equations are graphed as a straight line, while nonlinear equations are not.
<em>Evaluate 2x-4y for x=2 and y=4.</em>
Replace x with 2 and y with 4.
2(2)-4(4)
Simplify.
4-16
