in geometry class, there are several forms of an equation of a line that most students learn.<\/p>\n

you learn standard form, slope-intercept form, point-slope form, etc., but for basically every single question that the act math section asks you about lines on a coordinate plane, there\u2019s only one you really need to know. only one that is really useful.<\/p>\n

the winner is…slope-intercept form, or \"y.<\/p>\n

ding! ding! ding!<\/p>\n

slope-intercept form is so useful because, in order to answer many questions on the act, you will need to find: either the slope or the y-intercept, or you will be given the slope and a point and need to find the y-intercept, or something along those lines.<\/p>\n

if you put an equation in slope-intercept form,\"y, you will see this information instantaneously. in the equation \"y:<\/p>\n
