Write an equation of line in slope-intercept form and graph the equation.
Answer to Problem 33SGR
The, equation of line is
Graph of this line:
Explanation of Solution
Given information:
Slope of line
y-intercept of line
Formula used: Slope- intercepts form
where m is the slope and b is y-intercept
Solution:
Plug the value of slope (m) =-2 and y-intercept(b)=-9 of line in slope-intercept form
We get,
Therefore, the equation of line is
Graphing the equation:
Plot the y-intercepts first (0, -9)
Plot one more point by using =
Another point will be
Draw a line by joining the points (0,-9) and (1,7).
