Question

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

Answer 1

q = 10

Explanation:

`\text{slope} =-3=(q-4)/(-7-(-5)) =(q-4)/(-2) \\\Longrightarrow -3=(q-4)/(-2) \\\Longrightarrow \left( -3\right) * \left( -2\right) =q-4\\\Longrightarrow 6=q-4\\\Longrightarrow q=6+4\\\Longrightarrow q=10`
