In the line (y=-2x+10), what are the slope and (y)-intercept?
Answer and explanation
Correct answer: Slope (-2), (y)-intercept (10)
The slope-intercept form of a line is
\(y=mx+c\), where
\(m\) is the slope and
\(c\) is the (y)-intercept. Comparing
\(y=-2x+10\) with this form gives
\(m=-2\) and
\(c=10\). Hence, the slope is
(-2) and the (y)-intercept is
(10). Option C has the correct intercept but misses the negative sign of the slope. Exam tip: always check the sign of the coefficient of
\(x\).
