10) (9,-3); m=2
(a) y=2x-11
Plug in the variables that are constant on both the given line and the new one.
y=mx+b
-3=2(9)+b
Do not input b, as the y intercept is relative to the specific line, and not others.
-3=18+b
-3-18=b
-21=b
The y intercept of the new line is -21.
FINAL ANSWER::y=2x-21
(b) y=2x-21
Plug in the variables that are constant on both the given line and the new one.
y=mx+b
-3=2(9)+b
Do not input b, as the y intercept is relative to the specific line, and not others.
-3=18+b
-3-18=b
-21=b
The y intercept of the new line is -21
FINAL ANSWER::y=2x-21
Or equivalent to the original.
Hope this helps you solve the rest. ;)
Answer:
- y +5 = -5(x +6)
- y = -5x -35
Step-by-step explanation:
For a line with slope m through point (h, k), the point-slope form of the equation is ...
y -k = m(x -h)
For your point and slope, the line is ...
y +5 = -5(x +6)
__
Adding -5 and simplifying puts this in slope-intercept form.
y = -5x -30 -5
y = -5x -35
Answer:
A, B, E
Step-by-step explanation:
EC is 12 inches by pthag
AC is 17 becuase EC is 12 and AE is 5. 5+12 = 17
The parameter is 40 as 13 times two plus 5 times two is abt. 40

Answer:
(c) (4, 3)
Step-by-step explanation:
The next step in the solution of System B is to divide by 15 1/2. This will result in the equation ...
x = 4
The only answer choice that has x = 4 is the ordered pair (4, 3). That ordered pair is the solution to the system.
__
(15 1/2)x = 62 ⇒ (31/2)x = 124/2 ⇒ x = (124/2)/(31/2) = 124/31 = 4
