Since we know that

Put in (10, -2) as

Flip equation:

Whole equation:

Ans:

Hopefully I'm right ;/

#### 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"#

#rArry=-x+blarr" is the partial equation"#

#"to find b substitute "(10,-2)" into the partial equation"#

#-2=-10+brArrb=8#

#rArry=-x+8larrcolor(red)" in slope-intercept form"#
