What is the equation for a line with a slope of 2/3 that goes through (1, -3)?

y=2/3x +b

-3=2/3(1)+b

b=-11/3

y=2/3x+(11/3)

y=2/3x-11/3

Step-by-step explanation:

Given the slope and one point on the line we use the formula above.

it's equivalent, so we can say that its equal.

let's call the denominator x and the numerador is 18 less then denominator, x - 18.

multiply

2.x = 5.(x - 18)

2x = 5x - 90

90 = 5x - 2x

90 = 3x

x = 90/3

x = 30

so:
