Answer:
<h2>y = 3/4x + 5</h2>
Step-by-step explanation:
The slope-intercept form:
m - slope
b - y-intercept → (0, b)
The formula of a slope:
We have the points (4, 8) and (0, 5) → b = 5.
Calculate the slope:
Therefore we have the equation of the line:
Slope-intercept form is y = mx + b
So we can manage to do this:
(y - yo) = m.(x - xo)
Where (x, y) and (xo, yo) are points of this line, this way we can discover the slope.
(7 - 2) = m.(1 - 0)
5 = m
m = 5
So,
y = 5x + b
Now we still have to use (y - yo) = m.(x - xo), but this time we will put only 1 point and the slope.
(y - yo) = m.(x - xo)
(y - 2) = 5.(x - 0)
y - 2 = 5x
y = 5x + 2
So, this is the line in slope-intercept form.
Answer:
₹2835
Step-by-step explanation:
Working out discount of 10% of jeans at ₹1450:
10% of 1450 = 1450/10 = ₹145
the price would now be ₹1450 - ₹145 = ₹1305
Working out discount of 10% of a shirt at ₹850:
10% of 850 = 850/10 = ₹85
the price would now be ₹850 - ₹85 = ₹765
so the price of two shirts = ₹765 × 2 = ₹1530
the total the customer would have to pay:
₹1305 + ₹1530 = ₹2835
