Answer:
q = 10
Step-by-step explanation:
![\text{slope} =-3=\frac{q-4}{-7-(-5)} =\frac{q-4}{-2} \\\Longrightarrow -3=\frac{q-4}{-2} \\\Longrightarrow \left( -3\right) \times \left( -2\right) =q-4\\\Longrightarrow 6=q-4\\\Longrightarrow q=6+4\\\Longrightarrow q=10](https://tex.z-dn.net/?f=%5Ctext%7Bslope%7D%20%3D-3%3D%5Cfrac%7Bq-4%7D%7B-7-%28-5%29%7D%20%3D%5Cfrac%7Bq-4%7D%7B-2%7D%20%5C%5C%5CLongrightarrow%20-3%3D%5Cfrac%7Bq-4%7D%7B-2%7D%20%5C%5C%5CLongrightarrow%20%5Cleft%28%20-3%5Cright%29%20%20%5Ctimes%20%5Cleft%28%20-2%5Cright%29%20%20%3Dq-4%5C%5C%5CLongrightarrow%206%3Dq-4%5C%5C%5CLongrightarrow%20q%3D6%2B4%5C%5C%5CLongrightarrow%20q%3D10)
Well, you don't have any options.
But a mixed number for 12.16 would be 12 4/25. Hope it helps! :)
Answer:
slope = 2
Step-by-step explanation:
to calculate the slope m use the gradient formula
m = (y₂ - y₁ ) / (x₂ - x₁ )
with (x₁, y₁) = (1, - 5) and (x₂, y₂) = (4, 1 )
m =
=
= 2
Decimals are multiplied as if they were whole numbers, and then the decimal point is placed in the product. To find out where the decimal point should be placed, count the number of decimal places after the decimal point in each factor.
