AI Thread Summary
To find intercepts, identify the x-intercept and y-intercept from the given information. The x-intercept at -1 corresponds to the point (-1,0), while the y-intercept at 2 corresponds to the point (0,2). Plot these points on a graph and draw a line through them to represent the linear equation. This method effectively illustrates how to graph a line using intercepts. The discussion then transitions to solving a second problem related to finding intercepts.

For the first one, we are told the $x$-intercept is at $-1$, this means the point $(-1,0)$ is on the line. Likewise, we are told the $y$-intercept is at $2$, this means the point $(0,2)$ is on the line. Plot those two points, then draw the line that contains those two points.

Can you proceed with the second problem?
 

Thread 'Trigonometry problem of interest'

Seemingly by some mathematical coincidence, a hexagon of sides 2,2,7,7, 11, and 11 can be inscribed in a circle of radius 7. The other day I saw a math problem on line, which they said came from a Polish Olympiad, where you compute the length x of the 3rd side which is the same as the radius, so that the sides of length 2,x, and 11 are inscribed on the arc of a semi-circle. The law of cosines applied twice gives the answer for x of exactly 7, but the arithmetic is so complex that the...
