What is the slope and y- intercept of the line passing through (11,-3) and (7,9)
Misha Larkins [42]

Answer:

Slope is -3, y-intercept is 30

Step-by-step explanation:

You take the two points (11,-3) and (7,9), plug them into the formula y2-y1/x2-x2=m. Now, you have 9-(-3)/7-11 which gives you 12/-4, 12/-4 can be simplified into -3 which is your slope. To find y-intercept you must use the formula y=mx+b. Plug -3, your slope, into m, and any of the coordinates on your line into the y and x; I used (7,9). You solve for b from 9=-3*7+b. -3*7 gives you -21, now you have 9=-21+b, to get b by itself, you add 21 to both sides, 30=b. B is your y-intercept.

What is the x-intercept of the line with this equation 1/3x+y= -15?<br><br> (_,0)
Sidana [21]

( - 45, 0)

to find the x-intercept let y = 0 in the equation

x = 0 → \frac{1}{3} x = - 15

multiply both sides by 3

x = 3 × - 15 = - 45

x-intercept = ( - 45, 0)
