The equation of the line 2x - y = 9 expressed in slope-intercept form is y = 2x - 9 with a slope equal to 2.
The equation of a line can be expressed in three different forms: standard form, slope-intercept form, and point-slope form.
The slope-intercept form of the equation of a line is given by the formula:
y = mx + b
where m is the slope of the line
b is the y- intercept
Given the equation of the line 2x - y = 9, which is in standard form, transform it into slope-intercept form by isolating the variable y in one side.
2x - y = 9
y = 2x - 9
Hence, the equation of the line in slope-intercept form is y = 2x - 9 where the slope is equal to m = 2.
