What is the equition of a line?
a straight line equation is y=mx+c where x is the first value of an ordered pair and y is the second (x,y) m is the slope of that line and c is the y intercept , the point that the straight line cuts y-axis
What is the definition slope-intercept form?
In coordinate geometry, each point in the plane is identified by an ordered pair, (x,y) which are known as the coordinates of the point. The equation of any straight line in the coordinate plane can be written in the form y = mx + c so that the coordinates of each point on the line satisfies this equation (and the coordinates of a point outside the line doed not satisfies it). The equation in this form is known as the slope-intercept form. m is the slope and c is the intercept.
How do you plot an ordered pair whose both coordinates are complex numbers for example a plus bi and c-di here i is used for iota an imaginary unit a b c d are real numbers?
The two points would have to be plotted in 4-dimensional hyperspace. Conceptually straightforward, physically impossible.
If it is 100 yards from point A to point B and point C is 50 yards directly right of point A how far is it from point B to point C?
Assuming the line A to B is straight ahead, and perpendicular to the line A to C : A to B is 100 yds, A to C is 50 yds. If C is directly to the right of A, you have a right-angle triangle. The distance from C to B is the hypotenuse. To find the hypotenuse of a right-angle triangle, use the formula A² + B² = C². Using the formula: A² + B² = C² 50² + 100² = C² 2500 + 10000 = C² 12500 = C² sq rt of 12500 = C 111.80339 = C (The distance from point C to point B is 111.80339 yards)
