Graph each equation using the slope and the y-intercept. y = –4x – 2.5
1 answer:
Answer-
(See the attached picture below)
Step-by-step expression-
-2.5 is the y intercept so put a dot on that point on the graph. Then since the slope is -4, (the slope is negative), you want to rise (go up) 4 and run (go sideways) 1. Then just draw a line connecting those two dots. Happy studying :)

Answer:
A. (0, 1) and (2, -2)
B. Slope (m) = -³/2
C. y + 2 = -³/2(x - 2)
D.
E.
Step-by-step explanation:
A. Two points on the line from the graph are: (0, 1) and (2, -2)
B. The slope can be calculated using two points, (0, 1) and (2, -2):
Slope (m) = -³/2
C. Equation in point-slope form is represented as y - b = m(x - a). Where,
(a, b) = any point on the graph.
m = slope.
Substitute (a, b) = (2, -2), and m = -³/2 into the point-slope equation, y - b = m(x - a).
Thus:
y - (-2) = -³/2(x - 2)
y + 2 = -³/2(x - 2)
D. Equation in slope-intercept form, can be written as y = mx + b.
Thus, using the equation in (C), rewrite to get the equation in slope-intercept form.
y + 2 = -³/2(x - 2)
2(y + 2) = -3(x - 2)
2y + 4 = -3x + 6
2y = -3x + 6 - 4
2y = -3x + 2
y = -3x/2 + 2/2
E. Convert the equation in (D) to standard form:
Answer:
<h2>55 litres </h2>Step-by-step explanation:
Litres of milk sold by the dairy in April and May together = 3,355
So,
Litres of milk sold by the dairy per day = ?
To find this we have to do addition and division and have to go through the calender a bit :)
<h2>Let's solve it!!</h2>No. of days in April = 30 days
No. of days in May = 31 days
Therefore total no. of days in both the months = 30 + 31
= 61
Now,
Litres of milk sold by the dairy per day ( or in simple words the daily sale )
Si therefore 55 litres of milk was the daily sale.
Hope it helps you!!
