Explanation:
The equation of a line in
color(blue)"point-slope form"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=7/25" and " (x_1,y_1)=(14/5,13/10) substitute these values into the equation.
y-13/10=7/25(x-14/5)larrcolor(red)" in point-slope form" distributing and simplifying gives an alternative version of the equation.
y-13/10=7/25x-98/125
rArry=7/25x-98/125+13/10
rArry=7/25x+129/250larrcolor(red)" in slope-intercept form"
graph{7/25x+129/250 [-10, 10, -5, 5]}
