You use slope intercept (y=mx+b) to find yourb(y-intercept)
4=-4.5(0) + b
4=b therfore y=-4.5x + 4. Then you change it into standard form (Ax + By = C)
y= -4.5x +4
4.5x + y =4 is your answer.
Points: (2, -3) and (-2, 0) Slope: -3/4 Equation: y = -0.75x-1.5
It is (x + 2)^2 + (y + 3)^2 = 9
The equation works out as: y = 5x+7
Use the standard slope/intercept equation for a straight line and substitute the figures given in the question. y = mx + c .......m is the slope so we can now write y = -5x + c Substituting the ordered pair for x and y gives : 2 = (-5*0) + c = c The final equation is therefore, y = -5x + 2
Assuming the equation of the given line is y = 3x + 4, its gradient is 3.Therefore the gradient of the required line is 3. The line passes through (3, 1) and so its equation is y - 1 = 3*(x - 3) = 3x - 9 So y = 3x - 8
The standard form is: 5x - y + 4 = 0
I need step by step on my graphic calculator on how to write an equation
that's a verticle line cuz the x stays the same so it is X=-2
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.
The standard form of the equation is 2x - y + 5 = 0
(3,1)(3,2)
6666
If you mean of points of (3, -4) and (5, 1) then the equation works out as 2y=5x-23
If you mean a point of (0, 3) and a slope of 2 then the equation is y = 2x+3
Y=2/3x - 7
Points: (2, 2) and (6, 3) Slope: 1/4 Equation: y = 1/4x+3/2 In standard form: x-4y+6 = 0
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.
