Question

Write the equation of the line that has a slope of -2 and a y-intercept of -6.

Write the equation of the line that passes through the point (6, -2) and has a slope of -2/3.

Answer 1

y=-2x-6

Answer 2

is that the first 1 or the second 1 durviel?

Answer 3

Slope-intercept form is written \(\Large y = mx + c\) where m is the slope and c the y-intercept.
If you know the slope and a point, you can work out what the intercept is by evaluating the slope-intercept equation and solving for c.

Answer 4

first. i working on second

Answer 5

\[\Large \begin{array}{l}
y = mx + c\\
y = - \frac{2}{3}x + c\\
- 2 = - \frac{2}{3} \cdot 6 + c\\
- 2 + \frac{{12}}{3} = c\\
c = 2
\end{array}\]
