Slope-intercept form: y = mx + b [m is the slope, b is the y-intercept or the y value when x = 0 ---> (0, y) or the point where the line crosses through the y-axis]
To find the slope, use the slope formula (m):
and plug in the two points
(6, 8) = (x₁, y₁)
(9, 6) = (x₂, y₂)


Now that you found the slope, plug it into the equation
y = mx + b
To find b, plug in one of the points, I will use (6, 8)

8 = -4 + b Add 4 on both sides
12 = b Now plug in b into the equation

The height of a semisphere is equal a radius of this hemisphere.
But... if we can talk about the height of the hemisphere ;)
R = 0.8m = 80cm then height of hemisphere is equal 0.8m = 80cm.
Answer:
4f+4g
Step-by-step explanation:
Answer:
b = 37 degrees
Step-by-step explanation:
all of the angles on a triangle added up equal 180 degrees
111 degrees
32 degrees
111 + 32 = 143
180 - 143 = 37
b angle = 37 degrees
