Please could I have some help :)

As shown in picture,

Line A passes (3, 3) and (4, 5)

=> Gradient of line A = (y2 - y1)/(x2 - x1) = (5 - 3)/(4 - 3) = 2

Line B passes (0, 4) and (4, 0)

=> Gradient of line B = (y2 - y1)/(x2 - x1) = (0 - 4)/(4 - 0) = -4/4 = -1

Hope this helps!

:)

is there answer choices?

"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
