Answer:
y=4x + 7
Step-by-step explanation:
Line=y=ax+b
b = where the line crosses the y-axis (where x=0). Here, it's 7.
a= vertical distance ÷ horizontal distance.
You can take any pair of distances to a point on the line, for example (4,1) is easy to read in the graph.
x=0 to 1 (horizontal distance=1-0=1)
and
y= 0 to 4 (vertical distance= 4-0=4)
a=4÷1=4.
So, the answer is y=4x + 7 as a= 4 and b=7.
Answer: 2.083
Have a good day :D
Answer:
D. 38%
Step-by-step explanation:
3/8 as a percentage is 37.5% and that is rounded to 38%! :) 37% is close but it is not rounded making it not the best estimate, therefore it is not correct.
Answer:
y = -1/2x + 2
Step-by-step explanation:
y = 2x - 3. The slope here is 2. A perpendicular line will have a negative reciprocal slope. To find the negative reciprocal, just flip the slope and change the sign.
slope = 2 or 2/1.....flip it.....1/2....change the sign...-1/2. So our perpendicular line will have a slope of -1/2.
y = mx + b
slope(m) = - 1/2
(2,1)....x = 2 and y = 1
now we sub and find b, the y intercept
1 = -1/2(2) + b
1 = -1 + b
1 + 1 = b
2 = b
so ur equation is : y = -1/2x + 2 <===
and u can check it with ur points....(2,1)
y = 2x - 3
1 = 2(2) - 3
1 = 4 - 3
1 = 1 (yep...it checks out)
Answer:
D. (x-2)(x-4)
Step-by-step explanation:
The graph cross the x-axis in points with x-coordinates of 2 and 4
then 2 and 4 are roots of x² - 6x + 8.
