(a) \(\displaystyle{y}={b}_{{0}}+{b}_{{1}}{x}\)
where \(\displaystyle{b}_{{0}}\) is the y intercept
\(\displaystyle{b}_{{1}}\) is the slope
Slope = -0.75
y-intercept = -5
from the linear equation
\(\displaystyle{b}_{{0}}=-{5}\)
\(\displaystyle{b}_{{1}}=-{0.75}\)
(b) The slope is downward in graph. Because, the slope is negative value.
(c) Two point to graph:
