y = - 5/2 x + 5
State the slope of the line.
State the y-intercept of the line as an ordered pair.
Use slope-intercept form to graph the line.
Answer provided by our tutors
For any graphable equation, the software first manipulates it into its standard slope-intercept form before graphing;
For a linear equation, that form is "y=mx+b" where the slope "m" may then be determined by inspecting the equation:
For example, in the equation "y = - 5/2 x + 5"
"-5/2" is the correct value for "m" so the slope is m = -5/2
From the graph we see that the y-intercept is: (0, 5)
The slope-intercept intercept form is: "y = - 5/2 x + 5"
