How do you write the slope-intercept equation of a line with point (2,1) with slope -2/3?
The equation of a line in
where m represents the slope and b, the y-intercept.
Here we know m but have to find b.
#color(blue)"Partial equation"" is " y=-2/3x+b#
To calculate b, substitute x = 2 and y = 1 from (2 ,1) into the partial equation.
#rArry=-2/3x+7/3" is equation in slope-intercept form"#
