Every non-vertical straight line has the rule y = mx + c: the gradient m is the rate of change (how much y changes for each step of 1 in x) and c is the y-intercept, the value of y when x = 0. Reading a graph runs the same way in reverse: c is where the line cuts the vertical axis and m is the rise for one unit of run. Put two lines on the same axes and the pair has at most one shared point. Finding it is solving simultaneous equations: set the two rules equal, solve for x, substitute back for y. This is the real knowscape from knowhere, not a picture of one. Drag it. Watch what actually changes.
Every practical situation in here becomes a graph, and the graph is the situation in disguise: the slope is a rate, the intercept is a starting amount, the line is what happens next. Read those parts back into the real thing — cost, distance, fuel — and the model tells you what you didn't measure.
An equal-scale coordinate plane with a green line y = mx + c whose gradient and intercept you set, both intercepts and a rise-over-run triangle marked, and a dashed amber partner that is parallel, perpendicular or a fixed line y = −x + 2 whose intersection is ringed and solved algebraically from the live values.
knowhere maps every concept to what it rests on and what rests on it — 2 underneath this one, 4 built on top. Each one says why, in a sentence, not as an arrow on a diagram.
Each one is its own knowscape in the app — built for how a particular student takes things in, not one explanation handed to everybody.
Every HSC and VCE concept in knowhere is built like this one — mapped to your curriculum, never capped by it. Free for a week. No lock-in, cancel inside the week and pay nothing.
Free for a week, then one payment. It ends itself after the last exam — no subscription.
Free for a week, then a plan you can stop any time.
