y = 5x - 4
Substitute 6 in for y; then solve for x:
6 = 5x -4
10 = 5x
2 = x
So, the x-coordinate is 2.
Which of the following is the point-slope equation of the line with a slope equals -4 and a point of -2 3?
is an equation of a line in plane coordinate geometry. The coordinates of every point on that line satisfy the equation so there are an infinite number of solutions to the equation.
(5, -8)
It looks like this came from some multiple choice question, where you're given several choices. Take each choice and substitute the x and y coordinates into the equation. So for example the point is (0,3), then substitute in and get 2*0 + 3 which equals 3 and satisfies the equation, so the point is on the graph. If the point is (1,1) then 2*1 + 1 = 3 which satisfies the equation, so that point is also on the line. You want to find one where the left side does not equal 3, then that point is not on the graph of the line.
y = 1/3x+4/3
Which of the following is the point-slope equation of the line with a slope equals -4 and a point of -2 3?
A linear equation is the equation of a line and that consists of an infnite number of points. What you have, in x = -4 and y = -1/3, is a single point. A single point is not a line and so there cannot be a linear equation (suitable for a line) to represent a point.
Do you mean 0.4y+0.6y = 3y -36? If so then: y = 18
To check this, you substitute the values for x and y into the equation. At (1,2) x equals 1 and y equals 2 so substituting this in we get: x + 2y = 1 + 2(2) = 1 + 4 = 5 And since it equals 5 like in the original equation the point is represented by it.
The diagonal line collapses into a single point on that line.
It's the equation of a straight line. Every point on the line is a solution to the equation. There are an infinite number of them.
Point slope equation: Y=3X+12
it equals 1
35
It is a linear equation in two variables, x and y. Any point on the line defined by the equation will satisfy the equation and conversely, any ordered pair that satisfies the equation will represent a point, in the Cartesian plane, will be on the line.

1st equation: 3x+2y = 2 2nd equation: x-3y = -14 Multiply all terms in the 2nd equation by 3 and subtract it from the 1st equation:- So: 11y = 44 or y = 4 By substitution point of intersection is at: (-2, 4)
