Slope intercept form:
Y = mx + b
m = slope, b = y intercept
Given the slope of 4
Y = 4x + b
Plug in the point (3,8)
8 = 4(3) + b
8 = 12 + b, b = -4
Y intercept = -4

Solution: y = 4x - 4

What is the area of this question.

frez [133]

The area of a circle is \pi r^2, where r is the radius of the circle. The diameter of a circle is the length of a line that passes through the center of the circle and stops at the perimeter of circle. The radius of a circle is half the diameter. Divide the diameter by 2 to find the radius.
1. 2.8 m / 2 = 1.4 m
2 . $\pi (1.2m)^2$ : Plug in the value we just found for r.
3. $\pi 1.44m^2$ : Use the order of operations (PEMDAS).
4. $\pi * 1.44m^2 = ~4.52 m^2$
The area of the circle is equal to $4.52 m^2.$
