The phrase "roughly straight" is grammatically correct and can be used in written English.
It is often used to describe something that is not perfectly straight, but still relatively straight in comparison to something else. Example: The road was roughly straight, with only a few slight curves along the way.
System identification input was generated using a human pilot driving the catamaran on roughly straight line passes.
In stark contrast, drops with R = 2 mm follow roughly straight trajectories in a biased direction.
Imagine Herodotus on steroids, not rambling in a roughly straight line from Cyrus to Xerxes, but diverging onto untrodden paths that transmogrify into fluvial streams of consciousness.
In contrast to the complex, three-dimensional shape of myomeres in teleost fishes, the lateral hypaxial muscles of salamanders are nearly planar and their myosepta run in a roughly straight line from mid-lateral to mid-ventral.

Accordingly, point-to-point hand movements on a horizontal plane result in roughly straight-line paths with characteristic unimodal and symmetric "bell-shape" tangential velocity profiles [ 12].
The proposed technique refers to the dichromatic reflectance model, which states that the colors of a uniform lambertian object are roughly located around straight vectors going from the black to the body color, in relation to physical properties of the object.
As Fig. 3 shows, the ROC curve of the algorithm that gives random scores is roughly a straight line from the origin to the top right corner.
If (hat {S}(H t boldsymbol {hat {theta }}))) is the Kaplan-Meier estimate of (H t boldsymbol {hat {theta }})), then a plot of (-log hat {S}(H t boldsymbol {hat {theta }}))) versus (H t boldsymbol {hat {theta }})) should be roughly a straight line with unit slope when the model is adequate (Lawless 2002).
By 'playlisting' I mean a link to 'watch' the same video 150 times: roughly 9 straight hours of the same vid.
