Answer: the intercept is 8
The equation is
y = 4x/7 + 8
Step-by-step explanation:
The equation of a straight line can be represented in the slope-intercept form, y = mx + c
Where c = y intercept
Slope, m =change in value of y ontthe vertical axis / change in value of x on the horizontal axis
change in the value of y = y2 - y1
Change in value of x = x2 -x1
y2 = final value of y
y 1 = initial value of y
x2 = final value of x
x1 = initial value of x
From the information given,
Slope, m = 4/7
The points given are (0,8)
y = mx + c
8 = 4/7 × 0 +c
c = 8
The equation is
y = 4x/7 + 8
Answer:
64 lb = 29.029912 kg
Rounded to the nearest hundredth is 29.03 kg
hope this helps!
A is the correct choice.
This is based on the vertical line test. If you were to draw an imaginary vertical line on the graph, it would only intersect the graph at one point, which proves that all x values are different (a function).
3 is the total dollars 1 magazine cost
4 is the total of paperback books she bought
5 is the total dollars 1 paperback book cost
multiply 4 by 5 to get total cost of the 4 paperback books and add 3 of the total cost of the magazine to get the total cost of everything
