The equation of a line isy = 4x + 15.
What is the y-intercept of the line?

15

Step-by-step explanation:

The y-intercept is 15 because the equation of the line is in slope intercept form where y=mx+b

m is slope

b is the y- intercept

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:

the solution is the point

step-by-step explanation:

we have

> equation a

> equation b

adds equation a and equation b

substitute the value of x in equation b to find the value of y

the solution is the point
