2022年4月28日 · Presumably because the lines are plotted on the Cartesian plane. So the line intersects the y-axis at the point (0, y). The standart form of the equation of a line is y = ax + bx + c. If you replace x with 0, then y = c. Thus, the y-intercept point is (0, c).

2022年4月28日 · yes, but it is a lot easier if you keep it in fractions (easier to graph) mind you, standard form doesn't allow fractions.

2022年4月28日 · So that you have an equation = to 0 and can manipulate it in one variable. Y = 2 X - 4 2X - 4 = 0 2X = 4 X = 2 check the graph and see that this is true. Works for all such functions.

Because it is at the point where it crosses the y-axis, which is at value 0.

2022年4月28日 · The velocity at the starting point (when t = 0).

2022年4月28日 · No. Use the vertical line test along the Y axis and if the line is crossed more than once, you know that it isn't a function.

2022年4月28日 · no, a perpindicular is two lines with one interseption and where the lines meet they create 4 90 degree angles the lines create a t shepe.

2022年4月28日 · Draw a line of best fit through the plotted points which will give the y intercept. Draw a right angle triangle under the line which will be the triangles hypotenuse. Divide the vertical units of the triangle by the horizontal units which will give the value of the slope.

2022年4月28日 · Faith is not about having all the answers, but learning to ask the right questions.y = 2x + 3

2022年12月16日 · An x-intercept is the value where a graph of a line crosses the x-axis. I am not sure how a fraction could constitute a line and, therefore, how it could cross the x-axis.
