Answer:
the density of the iron is 7.9 g /cm^3
Step-by-step explanation:
The computation of the density of the iron is shown below:
Density = weight ÷ volume
= 474 ÷ (5 × 3 × 4)
= 474 ÷ 60
= 7.9 g /cm^3
Hence, the density of the iron is 7.9 g /cm^3

Answer:
The equation of the line is y = 3/2x + 5/2
Step-by-step explanation:
To find the equation of this line, start by using the two points with the slope formula to find the slope.
m(slope) = (y2 - y1)/(x2 - x1)
m = (4 - 1)/(1 - -1)
m = 3/(1 + 1)
m = 3/2
Now that we have the slope, we can use that and either point in point-slope form to find the equation.
y - y1 = m(x - x1)
y - 4 = 3/2(x - 1)
y - 4 = 3/2x - 3/2
y = 3/2x + 5/2
