2017年3月9日 · See explanation Method 1: Substitute values into x and apply the calculation y=(-2)xx" whatever value you chose" Draw a line connecting the points extending it to the edge of the graph paper. You may use a minimum of two values but I would suggest 3. If all three do not sit on the line then your maths is wrong somewhere. Method 2: What are called critical points for …

2017年10月23日 · See a solution process below: First, solve for two points which solve the equation and plot these points: First Point: For x = 0 y = 2 * 0 y = 0 or (0, 0) First Point: For x = 2 y = 2 * 2 y = 4 or (2, 4) We can next plot the two points on the coordinate plane: graph{(x^2+y^2-0.025)((x-2)^2+(y-4)^2-0.025)=0 [-10, 10, -5, 5]} Now, we can draw a straight line through the …

2016年12月23日 · See Explanation 1. The way to graph this with plotting points is that you choose random values for x and you can find out what your y value becomes. 2. For example let's pick 1, 3, and 5 for our x values. If you plug in those x values into the function y=-2x, you get: y=-2(1) so your y equals -2. Therefore your point on the graph is (1, -2). y=-2(3) which equals -6. …

2018年3月14日 · Refer to the explanation. Graph: y=-2x is a linear equation in slope-intercept form: y=mx+b, where: m is the slope and b is the y-intercept. Determine the x- and y-intercepts. The x-intercept is the value of x when y=0, and the y-intercept is the value of y when x=0. According to the slope-intercept equation, the y-intercept in the given equation is 0, and the …

2016年7月25日 · y=2x-5 is a line. Determine the two points that this line intersects with the axes then connect these points to graph it. Given y=2x-5 Set y=0 then solve for the abscissa y=2x-5 0=2x-5 2x=5 x=5/2 We now have the point (5/2, 0) Set now x=0 then solve for the ordinate y=2x-5 y=2(0)-5 y=-5 We now have the point (0, -5) We now simply draw a line passing thru the two …

2018年3月1日 · The x-intercept is (0,0). The y-intercept is (0,0). This means that the line passes through the origin. The x-intercept is the value of x when y=0. Substitute 0 for y and solve for x. 0=2x Divide both sides by 0. 0/2=(2x)/x Simplify. 0=x x-intercept: (0,0) The y-intercept is the value of y when x=0. Substitute 0 for x and solve for y. y=2(0) Simplify. y=0 y-intercept: (0,0) …

2018年3月20日 · How do you find the slope and y intercept of #y = 2x#? Algebra Graphs of Linear Equations and Functions Slope-Intercept Form. 1 Answer

2018年6月16日 · "see 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 y-intercept" • " let ...

2018年3月29日 · Slope is 2 The slope-intercept form is y = mx + b where m is the slope value. In the equation y = 2x, the m value is 2. Therefore, 2 is the slope.
