Lubov Fominskaja [6]

Answer:

1/3

Step-by-step explanation:

Slope = ( y₂ - y₁ ) ÷ ( x₂ - x₁ )

y₂ = 9

y₁ = 7

x₂ = 4

x₁ = -2

y₂ - y₁ = 9 - 7 = 2

x₂ - x₁ = 4 - -2 = 6

2 ÷ 6 = 1/3

3) An existing track is perpendicular to y=1/2x + 2 and passes through B(7,5)
stira [4]

Answer:

2. y=\frac{1}{2}x +3

Step-by-step explanation:

2. The line will be parallel to the current track which means they have the same slope. To write the equation, use the slope m=1/2 and the point (2,4) in point slope form:

y-y_1=m(x-x_1)\\y-4=\frac{1}{2}(x-2)

This is the equation of the line. You can convert it to slope intercept form:

y-4=\frac{1}{2}(x-2)\\y-4 = \frac{1}{2}x -1 \y=\frac{1}{2}x +3
