Equation: y = 3x

y = 3

Step-by-step explanation:

y ∝ x

y = Kx

9 = 3K

K = 9/3 = 3 Substitute y and x value to find K

y = 3x

Equation: y = 3x

x = 1

y = 3(1)

y = 3

Hope this helps!

Find the equation of the line with slope m=−34 that contains the point (8,−9).
asambeis [7]
Y=mx+b

subbing in m=-34
y=-34x+b

subbing in x=8 and y=-9
-9=(-34)(8)+b

solve for b:
b= 263

therefore, the equation of the line is
y=-34x+263
