2017年6月6日 · graph{y=4x+1 [-10, 10, -5, 5]} Since the equation is linear/straight in the form y=mx+c, you can determine the slope/gradient (m) and y-intercept (c). m=4 c=1 To graph this equation, you'll need to find 2 points on the line and join them together. We know one of the points is (0, 1) as the y-intercept is 1. You can find another point by substituting an arbitrary number …

2017年3月2日 · See explanation For a strait line graph you technically only need two points. It is better to have 3 or more. I would suggest 3. The logic behind this is that if all the points do not line up when you draw a line through them then you have a wrong calculation some ware. You may chose to determine what is called critical points and use those (just 2) or you may chose …

Since this tells us that the y-intercept is .Remember the y-intercept is the point where the graph intersects with the y-axis So we have one point Now since the slope is comprised of the "rise" over the "run" this means Also, because the slope is , this means: which shows us that the rise is 4 and the run is 1.

2017年11月12日 · A line passing through (0,-1) and (4,0) graph{1/4x-1 [-7.82, 12.18, -4.6, 5.4]} We need to find two points, then join up the line. The natural points to go for are those on the x-axis and the y-axis. To find the point where it crosse the y-axis: Let x=0 y=1/4(0)-1 y=-1 :. crosses at (0,-1) You can also tell this from the value of c from the general equation y=mx+c, as, if x=0, …

\[y=4x-1\] +. > < ...

this equation is for a line with a slope of 4 & a y intercept of 1 [point is (0,1). now setting y=0 and solving for x we have 0=4x+1 or 4x=-1 or x=-1/4 thus we have a second point (-1/4,0) now plot theses two points and draw a line between them & you have the line represented by …

2018年5月2日 · In the table above, I have chosen x to be -5, -2, 0, 2, 5 and seen what happen when I replaced these numbers with x in y=-4x+1. One calculation will for example be, y=-4*(-5)+1=21 Which basically means that when x=-5 the y-axis will be at 21. Another is , y=-4*(2)+1=-7 Which means that when we choose x=2 we will get a point on the y-axis being ...

2017年11月1日 · Passes through (1/4,0) and (0,-1) Basically, this is a straight line in the form y=mx+b Our gradient m is 4 which is positive, so our straight line slopes to the right You need to solve the equation to see where your line crosses the x and y axis. To find y is easy Let x=0 so y=4(0)-1 Giving us y=-1 So now we know our graph passes through y=-1 ...

2016年4月13日 · graph{y=4x [-10, 10, -5, 5]} Graph y=4x First, determine your slope and y-intercept. (Your equation is in slope-intercept form) Slope-intercept Form: y=mx+b m is the slope b is the y-intercept In your equation, the slope is 4 and the y-intercept is 0. Because your y-intercept is 0, place your first point at (0,0). Your second point should be at (1,4) because the …
