In general, if a line passes through the points (a, b) and (c, d), its equation can be written as:

y - b = [(d - b)/(a - c)](x - a)

In this case, however, the formula is not necessary -- and in fact, attempting to apply it in its current form would result in a division by zero error. Instead, however, we can simply note that from (-2, 9) to (-2, 7) the x-coordinate does not change. This can only be the case if the line is vertical, meaning that the x-coordinate never changes. The line can therefore be represented by the equation x = -2.

What is the solution to the equation y equals -2.5?

The equation y = -2.5 represents a horizontal line on the Cartesian plane passing through the point (-2.5, 0). This line is parallel to the x-axis and has a slope of 0. The solution to this equation is all real numbers on the y-axis that have a value of -2.5.


What is the graph of the equation -5x plus 2y equals 2?

A straight line through the points (0, 1) and (-0.4, 0).


How do you know the relationship between x and y is proportional?

The answer depends on how the information is presented. If in the form of a graph, it must be a straight line through the origin. If in the form of an equation, it must be of the form y = cx.


How do you find the equation of a parabola in standard form with x intercepts at -2 and 6 passing through 1 and 8?

Since we know the intercepts, its best to solve the general form first and then convert to the standard form. The intercepts tell us that for some constant, a y=a*(x+2)(x-6) We also know that the parabola must run through a given point (1,8) so we can plug that value in to get our value of a 8=a*(3)(-5) a=-8/15 Next, expand the formula and start moving numbers around until you are in standard form y=-8/15*(x²-4x-12) y=-8/15*((x-2)²-16) y=-8/15*(x-2)²+128/15


What is the equation of the axis of symmetry y equals x2 - 8x plus 16?

y = (x-4)(x-4) * * * The factors above are shown correctly. The axis of symmetry is the vertical line passing through the vertex, which is the point located at (4, 0). The equation of that line is x = 4, which is the answer you requested.

4. Write an equation in standard form for a line satisfying the given condition. Through -2 and 9 and -2 and 7.?

The standard form is Ax + By = C. The slope of the line is (9-7)/(-2 - (-2)) or 2/0. This indicates that this is a vertical line whose x intercept is -2. The equation of the line is then x = -2.

What is an equation of a line through (-5 1) with a slope of 7 standard form?

To find the equation of a line in standard form (Ax + By = C) that passes through the point (-5, 1) with a slope of 7, we can use the point-slope form first: (y - 1 = 7(x + 5)). Simplifying this gives (y - 1 = 7x + 35) or (y = 7x + 36). Rearranging to standard form results in (-7x + y = 36) or (7x - y = -36). Thus, the standard form of the equation is (7x - y = -36).
