What is an equation of the line that passes through the point (1,-7)(1,−7) and is parallel to the line 3x+y=33x+y=3?

a

step-by-step explanation:

"standard form:

3x2 + 14x − 10 = 0

solutions based on quadratic formula:

x1   = −14 − √ 142 − 4×3×(−10) /   2×3   = −14 − 2 × √ 79 /   6   ≈ −5.296

x2   = −14 + √ 142 − 4×3×(−10) /   2×3   = −14 + 2 × √ 79 /   6   ≈ 0.629

the answer is 15.50 for one mile

b) is slope: 0   y- intercept 15.5
