Answer: y=3x-7
Step-by-step explanation:
First you have to get the equation in slope intercept form by moving x over then dividing by -1 because y cannot be negative
Then since you're trying to find the line that is parallel you use the same slope which is 3x
You then plug in the points which is 2=3(3) + b for you are trying to find teh y intercept
You then solve as normal and get y=3x-7
I am pretty sure this is correct
Percent formula : is/of = %/100
18 is what percent of 20...
is = 18
of = 20
% = x
sub and solve
18/20 = x/100
cross multiply
(20)(x) = (100)(18)
20x = 1800
x = 1800/20
x = 90 <=== so 18 is 90% of 20
Plug 8 for y
8 = 2x + 4
Subtract 4
4 = 2x
Divide by 2
x = 2
Plug 16 for y
16 = 2x + 4
Subtract by 4
12 = 2x
Divide by 2
x = 6
Substitute 20 for y
20 = 2x + 4
16 = 2x
x = 8
Substitute 22 for y
22 = 2x + 4
18 = 2x
9 = x
So the values are 2, 6, 8, 9
Answer:
y = 5x - 7
slope = 5
Step-by-step explanation:
35x - 7y = 49
Subtract 35x from both sides.
-7y = -35x + 49
Divide both sides by -7.
y = 5x - 7
The equation is now in the slope-intercept form, y = mx + b, where m is the slope.
slope = m = 5
Answer:
(-a,b)
Step-by-step explanation:
You use midpoint formula which is (x1+x2/2),(y1+y2/2)
