A line with a slope of 2 and passes a point (4, 1). Please write the equation for this line in standard form. (standard form is Ax + By = C)
A line with a slope of 2 and passes a point (4, 1). Please write the equation for this line in standard form.?
First use slope intercept form-
y=mx+b, where m is the slope and b is the y intercept
y=2x+b
plug in the point-
1=2(4)+b
1=8+b
b=-7
Thus,
y=2x-7
Move the numbers around
2x-y-7=0
2x-y=7

Reply:First things first. We have a point and a slope, so we'll start with point-slope form and then try to transfer it to standard form.
y-ysub1=m(x-xsub1)
y-1=2(x-4)
Distribute
y-1=2x-8
Now, while it's the opposite of Ax+By=C, we'll move the variables to the right, and the constant to the left. We'll flip later, but the positive coefficent of x is needed for standard form.
-1-(-8)=2x-y
Flip and add
2x-y=7
Reply:I think it may be -2x + y = -7 but I'm not sure.
Reply:y=2x+4
if thats the y-intercept form then all u have to do is make it equal to zero.
-2x -4 + y =0
hope i helped :)
