Question

Which is the equation of a line that has a slope of -2/3 and passes through point

Answer 1

In slope-intercept form, y=mx+b, m is the slope and b is the y-intercept. Depending on where the line passes through the y axis, it would be y=-2/3x+b (the y intercept.)
Point/slope form is y-y sub1 = m(x-x sub1), again m is the slope of the line. (x sub1, y sub1) is a pair of any points that are on the line. For example, the equation y-2=3(x+1) is for a line with a slope of 3 and the line goes through the coordinates (-1,2).
Standard form is Ax+By=C, where A, B, and C are integers. For example, 2x+5y=7.
Hope this helps— hard to explain when I can’t see the line :/
