Using the y=mx+b equation (i forget what it’s exactly called) the equation will be y=-1x-1
Answer:
-⅓
Step-by-step explanation:
The formula for slope is y²- y¹/x²- x¹. Plug in the numbers for the equation and you have 4-5/1-(-2).
This gives you -1/3.
4 / 40 = 18 / x.....4 min to 40 gall = 18 min to x gall
cross multiply
(4)(x) = (40)(18)
4x = 720
x = 720/4
x = 180 gallons <==
Answer:
14
Step-by-step explanation:
Since we're given the conversion 24 cm for every 3 presents wrapped, we can divide our total amount of tape by this conversion, assuming a constant proportion.
Evren has 112 cm of tape. We can write the following proportion:
, where is the number of presents he can wrap with 112 cm.
Cross-multiplying, we have:
Answer:
<em>The equation of the straight line in point - slope form</em>
<em>y +1 = -2 ( x-2)</em>
Step-by-step explanation:
<u><em>Step(i):-</em></u>
Given points are C( 2,-1) and D(1,1)
Slope of the line
m = -2
<u>Step(ii):-</u>
Equation of the straight line passing through the point ( 2,-1) and having slope
m =-2
y - y₁ = m ( x- x₁)
y - (-1) = -2 ( x-2)
y +1 = -2 ( x-2)
<u><em>Final answer:-</em></u>
<em>The equation of the straight line</em>
<em>y +1 = -2 ( x-2)</em>
