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 a straight line graph are ...

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 two points to graph the ...

2018年4月8日 · #y=2x^2# #2y^2+y=2x^2+2y^2# #2(r(theta)sin(theta))^2+r(theta)sin(theta)=2(r(theta))^2# …

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.

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 point is (0,0). To determine the ...

2018年7月26日 · See answers below The given equation of line: y=2x+3 Comparing above equation with the standard slope-intercept form y=mx+c, we get Slope: m=2 Now, given equation can be re-written as 2x-y=-3 x/{-3/2}+y/3=1 Comparing above equation with intercept form: x/a+y/b=1, we get x-intercept: a=-3/2 y-intercept: b=3 Now, the given straight line intersects the coordinate axes at (-3/2, 0) & (0, 3 ...

2017年1月9日 · See the explanation. y=2x+1 Since this is the slope-intercept equation for a straight line, the table only needs two points. However, I'm going to determine 4 points (ordered pairs). Determine values of x, then calculate y.

2016年8月5日 · Which method do you use to solve the system of equations #y=1/4x-14# and #y=19/8x+7#? What are the 2 numbers if the sum is 70 and they differ by 11? How do you solve #x+y=5# and #3x+y=15# using the substitution method?

2017年3月22日 · The slope is #2# and the y-intercept is #3#. That means that starting point is #(0,3)# and as #x# increases by #1#, #y# increases by #2#. So some points would be: #(0,3)#, #(1,5)#, #(2,7)# Plot these three points and draw a line through them: graph{2x+3 [-10.25, 9.75, …
