What are the slope and the y intercept of the graph of the liner function shown on the grid

kow [346]

To find the slope use the Rise over Run rule
It rises 2 units and runs 1 unit, so your slope is
2 or 2/1

To find the y-intercept just find where the line crosses the y-axis
it crosses at the -4 mark

Your slope is 2 and y-intercept is -4

Total number of blue candies = 20 + 30 = 50
Number of blue candies without nut = 20

Probability of picking a blue candy without a nut = (Number of blue candies with nut) /(Total number of blue candies)

So, Probability of picking a blue candy without a nut = $\frac{20}{50} =0.4=40$ %

Thus, the correct answer is option A

m_a_m_a [10]

Answer: -12y²+7y²+20y-7

Step-by-step explanation:

Here, we need to use the concept of the FOIL method

First Outer Inner Last

----------------------------------------------------------

Given

(-3y+1)(4y²-y-7)

Expand Parenthesis using FOIL

-12y³+3y²+21y+4y²-y-7

Put like terms together

-12y³+(3y²+4y²)+(21y-y)-7

Combine like terms together

-12y²+7y²+20y-7

Hope this helps!! :)
