A line with slope 1/2 passes through the point (8, -1). What is the equation of this line?
OverLord2011 [107]
The equation would be: Y= 1/2x-1. Reasoning: Our equation format is Y=mx+b. Consider y to just be there for the mean time, but mx is where we insert our slope. We already know what our slope is in this equation (1/2) so that’s what we’ll insert, changing mx to 1/2x. B is where we put our Y. In this coordinate, our Y is -1 (keep in mind that a coordinate is set up as so: (x,y). Insert all our numbers to replace the variables and you get Y=1/2x-1

Y = 3/2x + 15, provide the x-y coordinates of the y-intercept and the x-intercept. Show your work.
Ray Of Light [21]

Answer:

The y-intercept is 15, which means the ordered pair is (0, 15), and the x-intercept is -10, which means the ordered pair is (-10, 0)

Step-by-step explanation:

To find the y-intercept it is quite easy. Since this is written in slope-intercept form, we can see the y intercept as the constant at the end of the equation.

The x-intercept can be found by inputting 0 for y and then solving for x.

y = 3/2x + 15

0 = 3/2x + 15

-15 = 3/2x

-10 = x

W = 40*\$10+(2*1.5*\$10)\\W=\$430

Jason's gross wages for the week are $430.
