How do find x and y intercepts without a graph?
If for example: y = 2x+4 Then: y-2x = 4 And when the value of x is 0 then the y intercept is 4 And when the value of y is 0 then the x intercept is -2
If mbad equals 5x plus 8 and mbcd equals 7x - 4 then mabc equals?

What is the straight line equation passing through points 4 and 0 when it is perpendicular to x plus 7y plus 4 equals 0?
x+7y+4 = 0 => y = -1/7x-4/7 The slope of the second equation is the reciprocal of the first equation with the minus sign changing to a plus sign. y = mx+c where m is the slope and c is the intercept on the y axis So: 7*4+c = 0 28+c = 0 c = -28 Therefore the perpendicular equation is: y = 7x-28 which can be expressed in the form of 7x-y-28 = 0
What are the intercepts for the line -4x y 8?
Unfortunately, limitations of the browser used by Answers.com means that we cannot see most symbols. If your question is not answered, please resubmit it, spelling out the symbols as "plus", "minus", "equals" etc. Also use ^ to indicate powers (x^2) or x-squared.Restate the question: What are the intercepts of the line -4x + y = 8?To find the y-intercept, let x=0: -4(0)+y=8 y=8To find the x-intercept, let y=0: -4x+(0)=8 -4x=8 -4x/(-4)=8/(-4) x=-2With a little practice, and if the numbers are 'nice', you can almost do this by just looking at the equation, or you can think of (0,_),(_,0). My students call this "googly eyes"!Also note that most texts define an intercept as a number ("the y-intercept is 8"), but it is rare to consider "The y-intercept is (0,8)." to be correct.
What is the centre and radius of the circle 4x2 plus 4y2 plus 16x -32y plus 71 equals 0?
Equation: 4x^2 +4y^2 +16x -32y +71 = 0 Divide all terms by 4: x^2 +y^2 +4x -8y +71/4 = 0 Complete the squares: (x+2)^2 +(y-4)^2 -4 -16 +71/4 = 0 So: (x+2)^2 +(y-4)^2 = 9/4 which is the radius squared Therefore centre of circle is at (-2, 4) and its radius is 3/2 or 1.5
What is the x-intercepts y equals 2x2 plus 2x - 4?
For the x intercepts, y = 0 ie 0 = 2x2 + 2x - 4 or x2 + x - 2 = 0 so that (x + 2)*(x - 1) = 0 So the intercepts are (-2,0) and (1,0)
Determine the coordinates of the x-intercepts for the quadratic equation 5x squared minus 21x plus 4 equals 0?
type you answer here!
What are the intercepts for the line x plus 2y equals 4?
y-intercept: 2 x-intercept: 4
What is intercepts of 4x plus 3y equals 6y?
4x + 3y = 6y 4x = 3y 4/3 x = y The slope is 4/3 and the y intercept is 0.
Find intercepts of xy equals 4?
There are no intercepts because the curve, xy = 4 is asymptotic. When x = 0 (where the y intercept would be) y is infinite, and conversely, when y = 0 x is infinite.
What is 1 plus 1 plus 1 plus 1-4 plus g equals?
1 plus 1 plus 1 plus 1 equals 1 times 4. 1 times 4 equals 4. 4 minus 4 equals 0. 0
Graph this equation 5x plus 10y equals 20?
for the equation:5x + 10y = 20, the two intercepts are:x = 0 , y = 2 or (0,2)y = 0 , x = 4 or (4,0)The graph is a straight line passing through the two intercepts (0,2) and (4,0)
What is the x intercepts of 7x squared plus 49x plus 84?
7x2+49x+84 = 0 Divide all terms by 7: x2+7x+12 = 0 Factorize: (x+3)(x+4) = 0 Therefore the x intercepts are -3 and -4
What is the x-intercepts of f of x equals x plus four divided by x?
Find the x-intercepts of f(x)=(x+4)/x The instructions simply mean that you should set f(x) equal to 0. To get the answer, you must set the numerator equal to zero, so x+4=0. Then x=-4 is the answer.
What are the slopes and y-intercepts of the following lines y equals 2x plus 4?
The slope is 2 and the y intercept is 4
How do you graph this function y equals 1 plus x plus 3?
You find the intercepts on the x and y axis: First, sub in x=0, giving you y=4. Then sub in y=0, giving you x=-4. So your intercepts are (0,4) and (-4,0). Plot these 2 points, and draw a line between them (you can do this since your function is a straight line, not a curve).
What are the x and y intercepts of -2x equals 20 plus 5y?
-2x = 20 + 5y-2x - 20 = 5y-2/5x - 4 = yX Intercept = (-10,0) or -10Y Intercept = (0,-4) or -4
