A construction company showed that the strength, y, of concrete, measured
by the percent of design strength attained, depends on the length of time, x,
(in days) since it was poured.
This value can be approximated by the equation y = 2.8x + 17.
a) What is the y-intercept? What does it mean in this setting? Your answer should tell something about the strength of concrete.
b) What is the slope? What does it mean in this setting? Your answer
should tell something about the strength of concrete.
c) How long does it take before y = 100?
