#y-0=4(x-7)#

Explanation:

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

#color(red)(bar(ul(|color(white)(2/2)color(black)(y-y_1=m(x-x_1))color(white)(2/2)|)))#
where m represents the slope and # (x_1,y_1)" a point on the line"#

#"here " m=4" and " (x_1,y_1)=(7,0)#

#rArry-0=4(x-7)larrcolor(red)" in point-slope form"#

#"or " y=4x-28larrcolor(red)" in slope-intercept form"#

#y = 4x-28#

Explanation:

y=mx+c
m=4
y=0
x=7
Therefore #0=4*7+c#
#0=28+c#
#c=-28#
Substitute m and c
#y=4x-28#
