Question

Name the slope and y intercept of 2x + 5y =20

Answer 1

Make y the subject,

\[y = \frac25x + \frac{20}{5}\]
\[y = \frac25x + 4\]

Answer 2

Slope = co-efficent of x.

Answer 3

slope: -2/5, y-int: (0,4)

Answer 4

wait, that's negative 2 over 5.
i did a typo.
sorry.

Answer 5

How'd it become negative?

Answer 6

solve the original equation for y.
5y = 20 - 2x
so
y = (20 - 2x)/5
or
y = -2x/5 + 4
