By converting the equation in point-slope form to slope-intercept form, we obtain #y=\frac{8}{9}x+\frac{8}{3}#

Explanation:

Given the slope of a line and a point on it, we can write its equation in point-slope form, denoted by:

#y-y_1=m(x-x_1)#

Where #m# is the slope, and #(x_1,y_1)# is a point on the line.

Let’s plug those values in:

#y-(-8)=\frac{8}{9}(x-6)#

#\implies y+8=\frac{8}{9}(x-6)#

We can now move around terms to convert this to slope-intercept form:

#y=8=\frac{8}{9}(x-6)#

#\implies y+8=\frac{8}{9}x-\frac{16}{3}#

#\implies y=\frac{8}{9}x+\frac{8}{3}#

#y=8/9x-40/3#

Explanation:

#"the equation of a line in "color(blue)"slope-intercept form"# is.

#color(red)(bar(ul(|color(white)(2/2)color(black)(y=mx+b)color(white)(2/2)|)))#

#"where m is the slope and b the y-intercept"#

#"here "m=8/9#

#rArry=8/9x+blarrcolor(blue)"is the partial equation"#

#"to find b substitute "(6,-8)" into the partial equation"#

#-8=(8/9xx6)+brArrb=-8-16/3=-40/3#

#rArry=8/9x-40/3larrcolor(red)"in slope-interceot form"#
