Question

Please help answer :)

Answer 1

Answer:

Step-by-step explanation:

1. You just plot the points

2. To plot the line you have to find the slope and y-intercept

Slope = $\frac{y_{2}-y_{1} }{x_{2}-x_{1} }$ = $\frac{30-15}{4-2}$ = $\frac{15}{2}$

Slope = $\frac{15}{2}$

Y-intercept = $y-y_{1}=m(x-x_{1} )$

Y-intercept: y - 15 = $\frac{-15}{2}$(x - 2)

y - 15 = $\frac{-15}{2}x$ + 15

Add 15 to both sides

y = $\frac{-15}{2}$x + 30 this is the equation of the line.

So you start with the starting point and then the slope!
