a) When we have the equation of a straight line, how do we find the x−intercept?Put y =0 and solve for x.b) How do we find the y−intercept?Put x =0 and solve for y.Problem 12. Mark the x- and y-intercepts, and draw the graph of ...
The graph of an equation, in other words, is the graph of its solutions. It is the picture of those values of (x, y) that make the equation -- that statement -- true.Every first degree equation -- where 1 is the highest exponent -- has as its graph a straight line. (We prove...

A particle moves along a straight line. The graph of the particle's velocity v(t) at time t is shown above for 0≤q t≤q m, where j, k, l, and m are constants. The graph intersects the horizontal axis at t=0, t=k and t=m and has horizontal tangents at t=j and t=l. ...
We study straight-line drawings of graphs with few segments and few slopes. Optimal results are obtained for all trees. Tight bounds are obtained for outerplanar graphs, 2-trees, and planar 3-trees. We prove that every 3-connected plane graph on n vertices has a plane drawing with at ...
A natural way to represent on the plane both a planar graph and its dual is to follow the definition of the dual, thus, to place vertices inside their corresponding primal faces, and to draw the dual edges so that they only cross their corresponding primal edges. The problem of ...
In finance, line graphs are used to create visual representations of values over time, including changes in the prices of securities. Understanding Line Graphs Line graphs use data point "markers," which are connected by straight lines. These data points, connected by straight lines, aid in visu...
straight line A line that does not bend or curve. The graph of a linear relationship is a straight line and is often presented in the form y=mx +c,where m is the slope,or gradient,of the line and cis the y-intercept (the point at which the line cuts the y-axis). 相关知识点:...
