I got Lines S and P for (a) (i) and Line S for (ii). I can't get (b) and (c). Help.
the gradient of a line is another word for the slope, namely the change in y coords over the change in x. it can be derived from the standarrd equation of a line, namely y = mx +b, where b is the gradient.
For the last one, think of the defnition of being pependicilar (they intersect at a right angle, the slope of one line = the negative inverse of the other)
good work on the other problems btw
the standard form is what the line was in before, y = mx + b is the slope-intercept form. m is the gradient. b is the y-intercept
that's correct
For the last one, think of the defnition of being pependicilar (they intersect at a right angle, the slope of one line = the negative inverse of the slope of the other line)
i kind of agree with you there, its the form everyone is most acquainted with, it should be called standardwhen you have your audience with the math gods, tell them to endow Jhevon with more mathematical powerbut ill consult the mathematical gods about that one later...
