Answer:
k = 4
Step-by-step explanation:
The graph represents y and x in direct proportion with equation
y = kx ← k is the constant of proportionality
To find k use the point (1, 4), that is x = 1, y = 4
k = 
= 
= 4
Answer:
HCF of 120 and 180 is 60 and hence a measuring tin of 60 litre volume should be bought.
Since we aren't told the length of the 3rd bar, focus solely on the lengths of the first 2 bars. Add together their lengths: 1.15 cm + 3.92 cm = 5.07 cm.
Answer:
y = 5x-14
Step-by-step explanation:
We should use point-slope form to form our equation:
y-1 = 5(x-3)
y-1 = 5x-15
y = 5x-14
Our equation is now in slope-intercept form.
