A line has a slope of 8 and crosses the y-axis at (0, 12). Express this line in slope intercept form.

y = 8x + 12

Step-by-step explanation:

The equation for all linear equations (slope-intercept form) is y = mx + b where m = slope and b = the y-intercept.

According to the information given, the slope is 8, and the y-intercept is 12. The y-intercept is 12 because the line touches the y-axis at (0,12).

That means that m = 8 and b = 12...

y = mx + b

y = 8x + 12

I hope this helps! Have a great day!

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:
