A line has a slope of –5 and a y-intercept of 9. What is the equation of the line in standard form?

Please answer!!
slope-intercept ... y = -5x + 9
adding 5x ... 5x + y = 9
adding 5x ... 5x + y = 9
Most authors of textbooks label them as follows
y = 6x -9 <----- y-intercept slope form
3x + 5y = 2 <---- standard form
6x - 2y + 7 = 0 <------ general form
check which notation your text uses.
You must practise to form one format into any of the other two.
in your case, from the given, we can immediately say
y = -5x + 9
or
5x + y = 9
or 5x + y - 9 = 0
y = 6x -9 <----- y-intercept slope form
3x + 5y = 2 <---- standard form
6x - 2y + 7 = 0 <------ general form
