In the equation you want to find, the constant on the right (the y-intercept) will be the one that lets the line go through the given point. Putting that point in the equation, we can solve for the intercept:
... 8 = (4/5)(-3) + b
Adding 2.4 to each side gives
... 10.4 = b
Your equation is ...
... y = (4/5)x + 10.4
_____
The constant 10.4 could be written 52/5 if you like.
Hello,
y=5/(6x-72)
==>6x-72≠0
==>x≠72/6
==>x≠12
Answer:
1a. Gradient =4
1b. y=4x-5
For x:
4x-5=0
x=5/4
therefore x=1.25
for y:
y=4 (1.25)-5
y=0
therefore y=0
coordinate = (1.25,0)
equation for parallel= y=4x
Step-by-step explanation:
for equation of parallel, it is said parallel lines has the same gradient therefore, gradient of parallel line =4
y-y1=m (x-x1)
where m=gradient=4
y1&x1 are the coordinates which is (0,0)
y-0=4 (x-0)
y-0=4x-0
therefore:
y=4x
hope that's okay
are you sure this is full question?
Answer:
triangle ABD> triangle BDC answer is B
Step-by-step explanation:
reason is because A-D is 5 while B-C is 4.5 the other sides are equal so ABD is larger
