Answer:

Step-by-step explanation:
Assuming this is a linear equation in the form of
, we can first solve for the slope using
, for these points, the slope would be
. Now we plug in the points to get the equation:
plugging in (7,5), we get
×
+ 
and solving for b, we get b = 
therefore, the equation of the line passing through (7,5) and (1,2) is
.

(Put what the first number is) x (the previous number) + 8 + 12 = ?
Answer:
3
Step-by-step explanation:
the equation would be 5 = 3(3) - 4
which is 9 - 4 = 5
The answer to this question is C.
Answer:
y = 2x + 2
Step-by-step explanation:
The equation ofa line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
y = 2x + 4 ← is in slope- intercept form
with m = 2
Parallel lines have equal slopes , thus
y = 2x + c ← is the partial equation
To find c substitute (3, 8) into the partial equation
8 = 6 + c ⇒ c = 8 - 6 = 2
y = 2x + 2 ← equation of parallel line
