Step 1 Take x = 0 and solve for y We will get 0 −y = 1 ⇒ y = − 1 So the first point of our consideration is (0, −1) Step 2 Next we take y = 0 and solve for x We get x −0 = 1 ⇒ x = 1 So the next point in our consideration is (1,0) So finding these 2 points and joining them through a line, we then extend the line on either sides to whatever length we see fitNow, choose an xvalue (besides x=0) and plot the point on the line y = − 3 5 x 1 that corresponds to this value Then, use these two points to graph the line The equation, y = 4 x − 3, is written in slopeintercept form, which is y = m x b, to find, x, the number of small seashells in the collection before the were added?
Example 1 Sketch the graph of 2x y = 3 Solution We wish to find several pairs of numbers that will make this equation true We will accomplish this by choosing a number for x and then finding a corresponding value for y A table of values is used to record the dataThe slope of a line containing the points P 1 (x 1, y 1) and P 2 (x 2, y 2) is given by Two lines are parallel if they have the same slope (m 1 = m 2) Two lines are perpendicular if the product of their slopes is l(m 1 * m 2 = 1) The pointslope form of a line with slope m and passing through the point (x 1, y 1) is y y 1 m(x x 1) Explanation one way is to find the intercepts, that is where the graph crosses the x and y axes ∙ let x = 0, in the equation for yintercept ∙ let y = 0, in the equation for xintercept x = 0 ⇒ y = 0 − 1 ⇒ y = − 1 ← yintercept y = 0 ⇒ x −1 = 0
Answer (1 of 10) Start off by understanding the equation Your equation is a linear or straight line equation Now, let's dissect it a bit The 1 is called your yintercept The yintercept of this line is the value of y at the point where the line crosses the y axis Now, look at the 2 only inIn this form, (x 1)^2, I usually set the inside part of the binomial equal to 0 x 1 = 0 When you solve that equation, it gives you the xvalue of the vertex This should be the "middle" value of your list of inputs so that you can be sure to get the symmetry of the graph well displayedLike if you got two oranges for five dollars y= 2 (x/5) where y is oranges and x is the amount of money you had Say you had dollars, the equation would become y=2 (/5) which equals y=2 (4) which equals y=8 , so you could get 8 oranges with dollars That was just a simple example
Y 4 = 4(x 1) A The graph is a line that goes through the points (1,4) and (0,0) BCheck this out y = \left x 1 \right \left x 2 \right So, equate both the linear expressions with 0 And the resulting value will be the intersection of the equation uAnswer (1 of 8) If x = 1 the numerator (top line) = 0 so y = 0 when x = 1 If x =– 1 the denominator (bottom line) = 0 which means y is infinite and this means there is a vertical asymptote at x = –1 If x is large then y = – 1 (a bit) and this means there is a horizontal asymptote of y = 1 A
