#y=7/4x+163/4#

Explanation:

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

#•color(white)(x)y=mx+b#

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

#"here "m=7/4#

#y=7/4x+blarrcolor(blue)"is the partial equation"#

#"to find b substitute "(-21,4)" into the partial equation"#

#4=-147/4+brArrb=16/4+147/4=163/4#

#y=7/4x+163/4larrcolor(red)"is an equation of the line"#
