B+c = 7 = 3 +4
a+b = 5 = 2 +3
so a = 2, b=3,c =4
axb + b xc = (2x3) + (3x4) = 6 + 12 = 18

Through: (2,-4), parallel to y=3x+24)

SVETLANKA909090 [29]

Answer:

y = 3x - 10

Step-by-step explanation:

Assuming you require the equation of the parallel line through (2, - 4)

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

y = 3x + 24 ← is in slope- intercept form

with slope m = 3

• Parallel lines have equal slopes, hence

y = 3x + c ← is the partial equation of the parallel line

To find c substitute (2, - 4) into the partial equation

- 4 = 6 + c ⇒ c = - 4 - 6 = - 10

y = 3x - 10 ← equation of parallel line
