Answer:
y = −4x + 2
Step-by-step explanation:
The slope intercept form of the equation for a line is ...
y = mx + b . . . . . . where m is the slope and b is the y-intercept (0, b)
Here, you are given a slope of -4 (m=-4) and a y-intercept of (0, 2), so b=2. When you put these values in place of the corresponding variables, you get ...
y = -4x +2
Answer:
Option (A)
Step-by-step explanation:
Let the equation of the line passing through a point (x', y') and slope 'm' is,
y - y' = m(x - x')
Slope of the line passing through two points (0, 5) and (4, -7),
m = 
= 
= -3
As slope of the line is negative, Options (A) and (B) will be the possible options.
Therefore, equation of the line passing through (4, -7) will be,
y - (-7) = -3(x - 4)
y + 7 = -3(x - 4)
Therefore, Option (A) will be the correct option.

Answer:
2.25 + 1 1/3=3.5833333 combined number of pounds of mulch and gravel sold.
2.25/3.583333 X 172=108 pounds of mulch that the supplier sells
(1 1/3) / 3.583333 X 172=64 pounds of gravel that the supplier sells.
Step-by-step explanation:
Let 'x' = pounds of gravel The ratio of mulch to gravel is given 2 1/4 / 1 1/3 Which equals 9/4 / 4/3 = 27/16
So the total gravel and much is equal to x + 27/16x = 172
Solving for 'x'
43/16 x = 172
x = 172 (16/43) = 64 pounds of gravel Mulch = 27/16x = 64 (27/16)= 108 pounds
