Answer:

#y=5x-15#

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"#

#"x-intercept " =3rArr(3,0)" is a point on the line"#

#"here " m=5" and " (x_1,y_1)=(3,0)#

substitute these values into the equation.

#y-0=5(x-3)#

#rArry=5x-15" is the equation of the line"#
