Answer:
equation B is linear. A linear equation will not contain exponents.
Step-by-step explanation:
Answer:
b and c
Step-by-step explanation:
They both follow the formula of a linear function: y = mx + c, where m is the gradient and c is the y-intercept.
When you rearrange:
a. y = 60/x (this is a reciprocal function)
b. y = x - 1 (says that this linear function has a gradient of 1 and cuts the y-intercept at (0,-1))
c. y = 3x/2 -5/2 (says that this linear function has a gradient of 3/2 and cuts the y-intercept at (0, 5/2))
