Hello from MrBillDoesMath
Answer: y = 3x -10
Discussion
:
Since the line is parallel to y = 3x + 7, the lines have the same slope. This means the point intercept of the parallel line is
y = 3x + b
As the new lines passes through (2, -4). substitute the x and y values of that point in the new equation:
(-4) = 3 (2) + b =>
-4 = 6 + b => (subtract 6 from each side)
-4 -6 = (-6 + 6) + b =>
-10 = 0 + b =>
b = -10
y = 3x -10 is the equation of the parallel line
Thank you,

Answer:
31°
Step-by-step explanation:
because angle a and angle b are complementary they equal 90 degrees in total
a+b=90
since angle a = 59°
59+b=90
so you use subtraction property of equality and subtract 59 from both side of the equal sign
59+b=90
-59 -59
b= 31°
y= 2x-10
y=4x-8
------------subtract
0 = -2x - 2
-2x=2
x = -1
y= 2x-10
y= 2(-1)-10
y = -2 - 10
y = -12
answer: x = -1 and y = -12 or (-1,-12)
