Given points P(-3,4) and Q(4,y) in a coordinate plane, for what value y of is the slope of the line through P and Q equal to 1/7?
For what value y of is the slope of the line through P and Q equal to 1/7?
Hello Guest!
\(m=\frac{y_Q-y_P}{x_Q-x_P}\)
\(\frac{1}{7}=\frac{y-4}{4-(-3)}\\ y-4=\frac{4+3}{7}\\ y=\frac{4+3}{7}+4\\ \color{blue}y=5\)
