A line has a slope of -3 and includes the point (-5,4) and (-7,q). What is the value of q

serious [3.7K]

Answer:

q = 10

Step-by-step explanation:

$\text{slope} =-3=\frac{q-4}{-7-(-5)} =\frac{q-4}{-2} \\\Longrightarrow -3=\frac{q-4}{-2} \\\Longrightarrow \left( -3\right) \times \left( -2\right) =q-4\\\Longrightarrow 6=q-4\\\Longrightarrow q=6+4\\\Longrightarrow q=10$

7y-12-3y+9=0 help please

nasty-shy [4]

Simplify. Combine like terms

7y - 3y = 4y

-12 + 9 = -3

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

4y - 3 = 0

Isolate the y. Note the equal sign. What you do to one side, you do to the other side. Do the opposite of PEMDAS.

4y - 3 (+3) = 0 (+3)

4y = 3

4y/4 = 3/4

y = 3/4

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

y = 3/4 is your answer

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

hope this helps
