Answer to Question #209089 in Algebra for Mya

Question

State the domain, range, and y-intercept of points(1.6,5) (-3,1)

Answer 1

Gradient , $m= \frac{\triangle y}{\triangle x}= \frac{5-1}{1.6-(-3)}= \frac{20}{23}$

Equation $\frac{20}{23}=\frac{y-1}{x+3} \implies y= \frac{20}{23}x+\frac{83}{23}$

Therefore, Domain $\left(-\infty \:,\:\infty \:\right)$

Range $\:\left(-\infty \:,\:\infty \:\right)$

y-intercept of points $\left(0,\:\frac{83}{23}\right)$
