X and Y coordinates - 🧠 ANSWER ✔✔The x coordinate is a given number
of pixels along the horizontal axis of a display starting from the pixel (pixel
0) on the extreme left of the screen. The y coordinate is a given number of
pixels along the vertical axis of a display starting from the pixel (pixel 0) at
the top of the screen.
, x-intercept - 🧠 ANSWER ✔✔the x-coordinate of a point where a line, curve,
or surface intersects the x-axis.
Slope of a line - 🧠 ANSWER ✔✔The slope of a line (also called the gradient
of a line) is a number that describes how "steep" it is.
the slope or gradient of a line is a number that describes both the direction
and the steepness of the line.
point-slope form - 🧠 ANSWER ✔✔the equation of a straight line in the form
y − y1 = m(x − x1) where m is the slope of the line and (x1, y1) are the
coordinates of a given point on the line — compare slope-intercept form.
linear equations - 🧠 ANSWER ✔✔an equation between two variables that
gives a straight line when plotted on a graph.
square function - 🧠 ANSWER ✔✔square map is a function defined on all
real numbers that sends any real number to its square, i.e., its product with
itself
Interpolation - 🧠 ANSWER ✔✔Interpolation is an estimation of a value
within two known values in a sequence of values.
