The slope-intercept form: y = mx + b
m - slope
b - y-intercept
We have y-intercept b = -2, therefore y = mx - 2.
The x-intercept = 3 is for y = 0. Substitute:
0 = m(3) - 2 <em>add 2 to both sides</em>
2 = 3m <em>divide both sides by 3</em>
m = 2/3
Therefore y = 2/3 x - 2.
The standard form: Ax + By = C.
2/3 x - 2 = y <em>add 2 to both sides</em>
2/3 x = y + 2 <em>subtract y from both sides</em>
2/3 x - y = 2 <em>multiply both sides by 3</em>
<h3>2x - 3y = 6</h3>
Answer:
The answer is
<h2>1520.5 cm²</h2>
Step-by-step explanation:
Surface area of a sphere is given by
S = 4πr²
where r is the radius
From the question r = 11cm
So the surface area of the sphere is
4π(11)²
= 4(121)π
= 484π
= 1520.5308
Which is
1520.5 cm² to the nearest tenth
Hope this helps you

Answer:
temperature of city a=5
temperature of city b=4
Step-by-step explanation:
Given:
Let temperature of city A= a
temperature of city B=b
As given:
4a=8+3b
a-2b=-3
rearranging 2nd equation we get:
a=-3+2b
substituting above in 1st equation we get:
4(-3+2b)-3b=8
8b - 12 = 3b + 8
8b-3b=12+8
5b = 20
b = 4
Now substituting b=4 in 4a = 8 + 3b
, we get
4a = 8 + 3b
4a = 8 + 3(4)
4a = 8 + 12
4a = 20
a = 20/4
a = 5
temperature of city a and city b on that day is 5C and 4C respectively!
