1 Which equation represents a linear function?
5
Mr. Carr is hiring a plumber to repair his
sink. Plumber W charges $97.50 per hour
and an additional $26.35 for the parts
needed. The cost of plumber T is shown in
A 2xy + y = 9
© 3y + x2 + x = 0
B y = 12Vx - 5
D 4x + 2(y - 1) = 0
the table.
Plumber T
2 Write the slope-intercept form of the
equation of the line with a slope of -
that passes through the point (15, -).
